Patent ID: 7573948

Claim:
A radio frequency (RF) transmitter, comprising: a baseband processor for digitally processing outgoing data, wherein the baseband processor is operable to produce an analog complex modulated baseband signal; and a radio processor, including: a complex analog-to-digital converter (ADC) connected to receive the analog complex modulated baseband signal, wherein the analog-to-digital converter is operable to convert the analog complex modulated baseband signal to a digital complex modulated baseband signal; a demodulator connected to receive the digital complex modulated baseband signal, wherein the demodulator is operable to demodulate the digital complex modulated baseband signal to produce a demodulated digital signal; a digital processor connected to receive the demodulated digital signal, wherein the digital processor is operable to process the demodulated digital signal to produce a processed modulated digital signal; a digital-to-analog converter (DAC) connected to receive the processed modulated digital signal, wherein the DAC is operable to convert the processed modulated digital signal to a continuous waveform signal; a filter connected to receive the continuous waveform signal, wherein the filter is operable to produce a filtered signal, and a translational loop connected to receive the filtered signal, wherein the translational loop is operable to convert the filtered signal to a Radio Frequency (RF) transmit signal.
