A 0.4-6 GHz Receiver for LTE and WiFi

Abstract

A universal receiver employs a feedback method to alleviate noise-linearity trade-offs and a new harmonic rejection (HR) method that does not require accurate phase matching. Realized in 28-nm CMOS technology, the prototype provides channel selection filtering at RF for channel bandwidths from 200 kHz to 160 MHz and exhibits a noise figure of 2.1-4.2 dB with HR > 60.8 dB while drawing 49 mW.
