TLDR
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 thanks to a 2.5 V linear LNA and mixer-based RF blocker filter.Abstract:
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.read more

SAW-less analog front-end receivers for TDD and FDD
TL;DR: A SAW-less differential transceiver can be appealing if it has an NF close to that of classical transceivers and it can be very flexible, being usable for both FDD (where duplexers are differential) and TDD.
