A 65nm CMOS 60 GHz class F-E power amplifier for WPAN applications

Abstract

This work presents a two-stage 65nm CMOS 60 GHz power amplifier composed by a Class E power stage and a Class F driver stage, dedicated to low cost Wireless Personal Area Network (WPAN) applications. To provide a switching operation at 60 GHz, an output network with distributed elements is used instead of lumped elements. The simulation results show a saturated output power of 15 dBm with a peak PAE of 26% at 60 GHz. It achieves a gain of 15dB at 60 GHz.
