Abstract:	Two techniques are presented in this paper for a software-defined radio (SDR) receiver robust to out-of-band interference. Voltage gain is realized at IF simultaneously with low-pass filtering to mitigate blockers and out-of-band intermodulation distortion. A 2-stage polyphase harmonic rejection (HR) mixer concept robust to gain error achieves 2nd-6th HR of more than 60dB for 40 samples without trimming or calibration. A prototype 0.4-0.9G zero-IF receiver in 65nm CMOS has 34dB gain, 4dB NF, +3.5dBm IIP3 and +47dBm IIP2 while drawing 50mA from 1.2V.
