20.1 An Ultra-Compact Asymmetrically Load-Pulled Series Doherty Power Amplifier in 22Nm FDSOI CMOS with 25.3dBm P sat and 29.7% PAE 6dB for Ku-Band 6G FR3
Abstract
This paper presents an ultra-compact asymmetrically load-pulled series Doherty PA in 22 nm CMOS SOI with a single-footprint output combiner. A quantitative analysis of a single transformer as an impedance inverter enables a passive-network transformation to a single- footprint EM structure. In addition, an asymmetric load-pull concept is proposed. The PA achieves 25.3 dBm Psat, 1.56 W/mm2power density, up to 30% PAE6dB, and wideband modulation for 3GHz QPSK and 2GHz 64QAM.
