This paper describes the first linear multistage class-J power amplifier (PA) fabricated in a 2-
μm InGaP/GaAs HBT process for multi-band long-term evolution (LTE) applications. It …

This paper presents a method of improving efficiency for the two-stage Doherty power
amplifier (DPA) using the optimized current of the peaking amplifier. The DPA has a two …

A three-stage Doherty power amplifier (DPA) with a flat gain is represented. The driving
amplifier at an input of peaking cells is used to achieve high efficiency and flat gain to control …

A Doherty amplifier is described in which odd harmonics from the class‐C peaking amplifier
flow to the main amplifier to achieve class‐F operation, without the need for complicated …

The recent trends in communication systems make use of modulation schemes like 256-
QAM which offer excellent spectral efficiency but also exhibit from high Peak-to Average …

This paper reports the advanced design of an extended GaN HEMT Doherty power amplifier
(DPA). For high efficiency over a wide output power range, the DPA is designed using two …

A Doherty power amplifier (DPA) with a self‐adaptive biasing circuit is presented in this
letter. The proposed structure is integrated into the gate biasing network of the peaking …

Power amplifiers (PAs) have their highest efficiency when they are used at full power (0dB
back-off). For this reason, most PAs are used at 1dB compression point (P1dB), but this point …
