A 2.3GHz hybrid GaN power amplifier (PA) with $2 ^{nd}$ harmonic injection (HI) in the output is studied in terms of efficiency and linearity enhancement under a two-tone signal input. The $2 ^{nd}$ harmonic signal is obtained by frequency doubling o

The performance of RF and microwave transistors and MMICs can be significantly affected by parasitics presented by the package. This paper presents a technique to validate a package model by replacing the active device with a metal-oxide-semiconducto

This paper describes the design and implementation of a dual-band output matching network (OMN) to enable the design of a dual-band power amplifier. The three-port network transforms 50-Q loads and presents, in two separate bands around 3.5 and 5.9 G

This paper discusses design of in-package reactances that can optimize efficiency of power amplifier transistors by specific and well-defined harmonic terminations and pre-matching within the device package. The methodology uses a passive fundamental
