Patent ID: 7110726

Claim:
An RF ASIC for a subscriber communicator, comprising: a receiver section, including; means for receiving an RF communication signal; and means for downconverting and demodulating the received RF communication signal to provide analog quadrature components of the received signal at baseband; a transmitter section, including: means for upconverting and combining analog input quadrature modulation components to provide an RF communication transmit signal; and means for amplifying the transmit signal for driving an external power amplifier; and a CODEC for processing the analog baseband quadrature components of the received signal to provide I and Q digital output signals, and for processing I and Q digital input signals to provide the analog input quadrature modulation components for said upconversion, the codec including an analog to digital converter and a decimation filter arranged to receive signals from the analog to digital converter for processing received signals, the codec also including an interpolator and a digital to analog converter arranged to receive signals from the interpolator for processing signals to be transmitted.
