Abstract:
1. A wideband communications system including: a digital predistorter (DPD) operable to receive an input signal, wherein the DPD is characterized by a DPD bandwidth; a filter characterized by a filter bandwidth coupled to the output of the DPD, wherein the filter bandwidth is less than the DPD bandwidth; a digital-to-analog converter coupled to the output of the filter; a modulator coupled to the output of the digital-to-analog converter; a power amplifier coupled to the output of the modulator; a band-pass filter characterized by a band-pass bandwidth coupled to the output of the power amplifier; a down-converter coupled to the output of the band-pass filter; and an analog-to-digital converter (ADC) coupled to the output of the down-converter, wherein the ADC is characterized by a sampling rate value less than a value of the DPD bandwidth.
