Abstract

This article presents a low-loss fully passive harmonic rejection (HR) and blocker-tolerant mixer-first receiver (RX) for 5G new radio (NR) applications. This design exploits the codesign of charge-sharing and capacitor stacking to offer early HR and high-Q filtering at the antenna interface using only switches and capacitors. A prototype RX in 45-nm partially depleted silicon-on-insulator (PD-SOI) occupies 0.65 mm 2 and operates from 250 MHz to 2.5 GHz while consuming 32.4–54 mW. The proposed d
