A highly-linear software-defined radio operating from 400 MHz to 6 GHz is presented, with the purpose of removing any dedicated filtering at the antenna. Very high resilience to out-of-band interference is achieved thanks to a 2.5 V linear LNA and mixer-based RF blocker filter. The 2 mm2, 40 nm digital CMOS receiver achieves +10 dBm out-of-band IIP3 and >; +70 dBm calibrated IIP2 at 3 dB NF. It tolerates 0 dBm blockers at 20 MHz offset with acceptable blocker NF.
