A 39-GHz Doherty-Like Power Amplifier with 22-dBm Output Power and 21% Power-Added Efficiency at 6-dB Power Back-Off
Chen, Lang; Chen, Lisheng; Sun, Depeng; Sun, Yichuang; Pan, Yulin; Zhu, Xi (2024-01-08)The design of a Doherty-like power amplifier for millimetre-wave (mm-wave) applications is presented in this work. The designed power amplifier employs a novel symmetrical load-modulated balanced amplifier (S-LMBA) ... -
A 40-GHz Load Modulated Balanced Power Amplifier using Unequal Power Splitter and Phase Compensation Network in 45-nm SOI CMOS
Chen, Lang; Chen, Lisheng; Ge, Zeyu; Sun, Yichuang; Zhu, Xi (2023-06-08)In this work, a ten-way power-combined poweramplifier is designed using a load modulated balanced amplifier(LMBA)-based architecture. To provide the required magnitudeand phase controls between the main and control-signal ... -
A 90-GHz Asymmetrical Single-Pole Double-Throw Switch with >19.5-dBm 1-dB Compression Point in Transmission Mode Using 55-nm Bulk CMOS Technology
Chen, Lisheng; Chen, Lang; Ge, Zeyu; Sun, Yichuang; Hamilton, Tara; Zhu, Xi (2021-08-25)The millimeter-wave (mm-wave) single-pole double-throw (SPDT) switch designed in bulk CMOS technology has limited power-handling capability in terms of 1-dB compression point (P1dB) inherently. This is mainly due to the ... -
A W-Band SPDT Switch with 15 dBm P1dB in 55-nm Bulk CMOS
Chen, Lisheng; Chen, Lang; Ge, Zeyu; Sun, Yichuang; Hamilton, Tara; Zhu, Xi (2022-03-25)Power-handling capability of bulk CMOS-based single-pole double-throw switch operating in millimetre-wave and sub-THz region is significantly limited by the reduced threshold voltage of deeply scaled transistors. A unique ...
