• An IQ Demodulator-Based IF-to-Baseband Receiver with IF and Baseband Variable Gain and Programmable Baseband Filtering
  Сircuit Note CN-0320 December 2013 This circuit is a flexible, frequency agile, direct conversion IF-tobaseband receiver. A fixed conversion gain of 5 dB reduces the cascaded noise figure. Variable baseband gain is used to adjust the signal level. The baseband ADC driver also includes a programmable low-pass filter that eliminates out-of-channel blockers and noise. The bandwidth of this filter can be dynamically adjusted as the bandwidth of the input signal changes. This ensures that the ...
