   BACKGROUND OF THE INVENTION 
   1. Technical Field of the Invention 
   This invention relates generally to wireless communication systems and more particularly to integrated circuits of transceivers operating within such systems. 
   2. Description of Related Art 
   Communication systems are known to support wireless and wire lined communications between wireless and/or wire lined communication devices. Such communication systems range from national and/or international cellular telephone systems to the Internet to point-to-point in-home wireless networks. Each type of communication system is constructed, and hence operates, in accordance with one or more communication standards. For instance, wireless communication systems may operate in accordance with one or more standards including, but not limited to, IEEE 802.11, Bluetooth, advanced mobile phone services (AMPS), digital AMPS, global system for mobile communications (GSM), code division multiple access (CDMA), local multi-point distribution systems (LMDS), multi-channel-multi-point distribution systems (MMDS), radio frequency identification (RFID), Enhanced Data rates for GSM Evolution (EDGE), General Packet Radio Service (GPRS), and/or variations thereof. 
   Depending on the type of wireless communication system, a wireless communication device, such as a cellular telephone, two-way radio, personal digital assistant (PDA), personal computer (PC), laptop computer, home entertainment equipment, RFID reader, RFID tag, et cetera communicates directly or indirectly with other wireless communication devices. For direct communications (also known as point-to-point communications), the participating wireless communication devices tune their receivers and transmitters to the same channel or channels (e.g., one of the plurality of radio frequency (RF) carriers of the wireless communication system or a particular RF frequency for some systems) and communicate over that channel(s). For indirect wireless communications, each wireless communication device communicates directly with an associated base station (e.g., for cellular services) and/or an associated access point (e.g., for an in-home or in-building wireless network) via an assigned channel. To complete a communication connection between the wireless communication devices, the associated base stations and/or associated access points communicate with each other directly, via a system controller, via the public switch telephone network, via the Internet, and/or via some other wide area network. 
   For each wireless communication device to participate in wireless communications, it includes a built-in radio transceiver (i.e., receiver and transmitter) or is coupled to an associated radio transceiver (e.g., a station for in-home and/or in-building wireless communication networks, RF modem, etc.). As is known, the receiver is coupled to an antenna and includes a low noise amplifier, one or more intermediate frequency stages, a filtering stage, and a data recovery stage. The low noise amplifier receives inbound RF signals via the antenna and amplifies then. The one or more intermediate frequency stages mix the amplified RF signals with one or more local oscillations to convert the amplified RF signal into baseband signals or intermediate frequency (IF) signals. The filtering stage filters the baseband signals or the IF signals to attenuate unwanted out of band signals to produce filtered signals. The data recovery stage recovers raw data from the filtered signals in accordance with the particular wireless communication standard. 
   As is also known, the transmitter includes a data modulation stage, one or more intermediate frequency stages, and a power amplifier. The data modulation stage converts raw data into baseband signals in accordance with a particular wireless communication standard. The one or more intermediate frequency stages mix the baseband signals with one or more local oscillations to produce RF signals. The power amplifier amplifies the RF signals prior to transmission via an antenna. 
   While transmitters generally include a data modulation stage, one or more IF stages, and a power amplifier, the particular implementation of these elements is dependent upon the data modulation scheme of the standard being supported by the transceiver. For example, if the baseband modulation scheme is Gaussian Minimum Shift Keying (GMSK), the data modulation stage functions to convert digital words into quadrature modulation symbols, which have a constant amplitude and varying phases. The IF stage includes a phase locked loop (PLL) that generates an oscillation at a desired RF frequency, which is modulated based on the varying phases produced by the data modulation stage. The phase modulated RF signal is then amplified by the power amplifier in accordance with a transmit power level setting to produce a phase modulated RF signal. 
   As another example, if the data modulation scheme is 8-PSK (phase shift keying), the data modulation stage functions to convert digital words into symbols having varying amplitudes and varying phases. The IF stage includes a phase locked loop (PLL) that generates an oscillation at a desired RF frequency, which is modulated based on the varying phases produced by the data modulation stage. The phase modulated RF signal is then amplified by the power amplifier in accordance with the varying amplitudes to produce a phase and amplitude modulated RF signal. 
   As the desire for wireless communication devices to support multiple standards continues, recent trends include the desire to integrate more functions on to a single chip. However, such desires have gone unrealized when it comes to implementing baseband and RF on the same chip for multiple wireless communication standards. 
   Therefore, a need exists for an integrated circuit (IC) that implements baseband and RF of multiple wireless communication standards on the same IC die.

     FIG. 16  is a schematic block diagram of another embodiment of a Voice Data RF IC  70  includes the data RF section  236 , the voice RF section  238 , the interface module  234 , the voice baseband processing module  230 , the data baseband processing module  232 , the AHB bus matrix  94 , the microprocessor core  190 , the memory interface  90 , and one or more of a plurality of interface modules. The plurality of interface modules includes the mobile industry processor interface (MIPI) interface  192 , the universal serial bus (USB) interface  194 , the secure digital input/output (SDIO) interface  132 , the I2S interface  196 , the Universal Asynchronous Receiver-Transmitter (UART) interface  198 , the Serial Peripheral Interface (SPI) interface  200 , the power management (PM) interface  124 , the universal subscriber identity module (USIM) interface  120 , the camera interface  156 , the pulse code modulation (PCM) interface  202 , the video codec  204 , the second display interface  126 , the coprocessor interface  136 , the WLAN interface  140 , the Bluetooth interface  146 , the FM interface  150 , the GPS interface  152 , the camcorder interface  160 , and the TV interface  164 . 
     FIG. 17  is a schematic block diagram of an embodiment of a voice RF section  238  that includes a receiver section  270  and a transmitter section  272 . The receiver section is coupled to convert the inbound RF voice signal  258  into the inbound symbol stream  260 . 
   The transmitter section  272  includes a conversion module  274 , a modulation parameter module  276 , 1 st  up-conversion module  278 , a 2 nd  up-conversion module  280 , a combining module  282 , and a power amplifier circuit  284 . The power amplifier circuit  284  may include one or more power amplifier drivers coupled in series and/or in parallel and/or one or more power amplifiers coupled in series and/or in parallel. 
   In operation, the conversion module  274  and the modulation parameter module  276  receive the outbound voice symbol stream  254 , where each symbol is expressed as a hybrid coordinate having an in-phase component and a quadrature component. The conversion module  274  converts the in-phase component and the quadrature component of a symbol into a normalized I symbol  286  and a normalized Q symbol  288 . This may be done by setting the amplitude of the in-phase component and the quadrature component of the symbol to the same value. For example, the in-phase component is A 1  sin(ω d (t)) and the quadrature component is A Q  cos(ω d (t)), where A 1  and A Q  are the amplitudes of the in-phase and quadrature components, respectively. By setting the amplitudes A 1  and A Q  to the same value (e.g., 1 or A 0 ), then the normalized I symbol  286  would be sin(ω d (t)) and the normalized Q symbol  288  would be cos(ω d (t)). 
   The modulation parameter module  276  generates offset information  290  and transmit property information  292  from the outbound voice symbol stream  254 . In one embodiment, the offset information  290  corresponds to phase information of the symbol (e.g., Φ(t)), which may be calculated as tan−1(A Q /A 1 ). Alternatively, the offset information  290  may correspond to frequency information of the symbol. 
   The modulation parameter module  276  generates the transmit property information  292  as a power level setting or as amplitude modulation information. For example, if the data modulation scheme uses phase modulation (e.g., QPSK, GMSK) or frequency modulation (e.g., frequency shift keying) without amplitude modulation, then the transmit property information  292  would correspond to the power level setting. In the alternative to the modulation parameter module  276  generating the power level setting, the voice baseband processing module  230  may generate it. 
   If the data modulation scheme using both phase and amplitude modulation (e.g., 8-PSK, QAM) or both frequency and amplitude modulation, then the modulation parameter module  276  would generate the amplitude information. In one embodiment, the amplitude information (e.g., A(t)) is generated as the square root of (A 1   2 +A Q   2 ). 
   The 1 st  up-conversion module  278  combines the normalized I symbol  286  with the offset information  290  to produce an offset normalized I symbol  286  (e.g., sin(ω d (t)+Φ(t)). This signal is mixed with an in-phase local oscillation that has a frequency corresponding to the second frequency band (e.g., 1920-1980 MHz) to produce a 1 st  up-converted signal  296  (e.g., ½ cos(ω RF (t)−ω d (t)−Φ(t))−½ cos(ω RF (t)+ω d (t)+Φ(t))). The 2 nd  up-conversion module  280  combines the normalized Q symbol  288  with the offset information  290  to produce an offset normalized Q symbol  288  (e.g., cos(ω d (t)+Φ(t)). This signal is mixed with a quadrature local oscillation that has a frequency corresponding to the second frequency band and filtered to produce the 2 nd  up-converted signal  298  (e.g., ½ cos(ω RF (t)−ω d (t)−Φ(t))+½ cos(ω RF (t)+ω d (t)+Φ(t))). The combining module  282  combines the first and second up-converted signals  296  and  298  to produce an RF signal  300  (e.g., cos(ω RF (t)+ω d (t)+Φ(t))). 
   The power amplifier circuit  284  amplifies the RF signal  300  in accordance with the transmit property information  292 . In one embodiment, the transmit property information  292  is a power level setting (e.g., A p ) such that the outbound RF voice signal  256  may be expressed as A p *cos(ω RF (t)+ω d (t)+Φ(t)). In another embodiment, the transmit property information  292  is the amplitude information (e.g., A(t)) such that the outbound RF voice signal  256  may be expressed as A(t)*cos(ω RF (t)+ω d (t)+Φ(t)). 
     FIG. 18  is a schematic block diagram of an embodiment of a data RF section  236  that includes a receiver section  310  and a transmitter section  312 . The receiver section  310  is coupled to convert the inbound RF data signal  246  into the inbound symbol stream  248 . 
   The transmitter section  312  includes a conversion module  314 , a modulation parameter module  316 , 1 st  up-conversion module  318 , a 2 nd  up-conversion module  320 , a combining module  322 , and a power amplifier circuit  324 . The power amplifier circuit  324  may include one or more power amplifier drivers coupled in series and/or in parallel and/or one or more power amplifiers coupled in series and/or in parallel. 
   In operation, the conversion module  314  and the modulation parameter module  316  receive the outbound data symbol stream  242 , where each symbol is expressed as a hybrid coordinate having an in-phase component and a quadrature component. The conversion module  314  converts the in-phase component and the quadrature component of a symbol into a normalized I symbol  326  and a normalized Q symbol  328 . This may be done by setting the amplitude of the in-phase component and the quadrature component of the symbol to the same value. For example, the in-phase component is A 1  sin(ω d (t)) and the quadrature component is A Q  cos(ω d (t)), where A 1  and A Q  are the amplitudes of the in-phase and quadrature components, respectively. By setting the amplitudes A 1  and A Q  to the same value (e.g., 1 or A 0 ), then the normalized I symbol  326  would be sin(ω d (t)) and the normalized Q symbol  328  would be cos(ω d (t)). 
   The modulation parameter module  316  generates offset information  330  and transmit property information  332  from the outbound data symbol stream  242 . In one embodiment, the offset information  330  corresponds to phase information of the symbol (e.g., Φ(t)), which may be calculated as tan−1(A Q /A 1 ). Alternatively, the offset information  330  may correspond to frequency information of the symbol. 
   The modulation parameter module  316  generates the transmit property information  332  as a power level setting or as amplitude modulation information. For example, if the data modulation scheme uses phase modulation (e.g., QPSK, GMSK) or frequency modulation (e.g., frequency shift keying) without amplitude modulation, then the transmit property information  332  would correspond to the power level setting. As an alternative, the data baseband processing module  232  may generate the power level setting. 
   If the data modulation scheme using both phase and amplitude modulation (e.g., 8-PSK, QAM) or both frequency and amplitude modulation, then the modulation parameter module  316  would generate the amplitude information. In one embodiment, the amplitude information (e.g., A(t)) is generated as the square root of (A 1   2 +A Q   2 ). 
   The 1 st  up-conversion module  318  combines the normalized I symbol  326  with the offset information  330  to produce an offset normalized I symbol (e.g., sin(ω d (t)+Φ(t))  326 . This signal is mixed with an in-phase local oscillation  294  that has a frequency corresponding to the first frequency band (e.g., 890-915 MHz) to produce a 1 st  up-converted signal  336  (e.g., ½ cos(ω RF (t)−ω d (t)−Φ(t))−½ cos(ω RF (t)+ω d (t)+Φ(t))). The 2 nd  up-conversion module  320  combines the normalized Q symbol  328  with the offset information  330  to produce an offset normalized Q symbol (e.g., cos(ω d (t)+Φ(t)). This signal is mixed with a quadrature local oscillation  294  that has a frequency corresponding to the first frequency band and filtered to produce the 2 nd  up-converted signal  338  (e.g., ½ cos(ω RF (t)−ω d (t)−Φ(t))+½ cos(ω RF (t)+ω d (t)+Φ(t))). The combining module  322  combines the first and second up-converted signals  336  and  338  to produce an RF signal  340  (e.g., cos(ω RF (t)+ω d (t)+Φ(t))). 
   The power amplifier circuit  324  amplifies the RF signal  340  in accordance with the transmit property information  332 . In one embodiment, the transmit property information  332  is a power level setting (e.g., A p ) such that the outbound RF data signal  244  may be expressed as A p *cos(ω RF (t)+ω d (t)+Φ(t)). In another embodiment, the transmit property information  332  is the amplitude information (e.g., A(t)) such that the outbound RF data signal  244  may be expressed as A(t)*cos(ω RF (t)+ω d (t)+Φ(t)).

The interface module  374  conveys the outbound voice symbol stream  254  to the RF section  372  when the Voice Data RF IC  70  is in a voice mode. 
   The RF section  372  converts the outbound voice symbol stream  254  into an outbound RF voice signal  256  in accordance with the one or more existing wireless communication standards, new wireless communication standards, modifications thereof, and/or extensions thereof (e.g., WCDMA, etc.), where the outbound RF voice signal  256  has a carrier frequency in the second frequency band (e.g., 1920-1980 MHz). In one embodiment, the RF section  372  receives the outbound voice symbol stream  254  as Cartesian coordinates. In this embodiment, the RF section  372  mixes the in-phase components of the outbound voice symbol stream  254  with an in-phase local oscillation to produce a first mixed signal and mixes the quadrature components of the outbound voice symbol stream  254  to produce a second mixed signal. The RF section  372  combines the first and second mixed signals to produce an up-converted voice signal.

The RF section  372  combines the first and second mixed signals to produce an up-converted data signal. The RF section  372  then amplifies the up-converted data signal to produce the outbound RF data signal  244 . Note that further power amplification may occur after the output of the RF section  372 . 
   In other embodiments, the RF section  372  receives the outbound data symbol stream  242  as Polar or hybrid coordinates.
