## Abstract This article reports a high efficiency classโE power amplifier using a SiC MESFET, which is designed and tested at 2.14 GHz. To improve output power and efficiency by suppressing harmonic powers, an output matching circuit using the transmission lines is used. From measured results for
## Abstract This article introduces a new architecture for a highโefficiency linear transmitter using a pulse modulated envelope signal. The transmitter employs multilevel PWM to represent the baseband signal. By using multilevel PWM, the efficiency of the power amplifier can be improved compared w
## Abstract The design and fabrication of a highโefficiency inverse classโF power amplifier using a 10โW gallium nitride (GaN) highโelectron mobility transistor at 1 GHz is presented. The output load network has been used to control harmonic components for highโefficiency operation. The measurement
## This paper reports the development of a high efficiency and compact power amplifier using an AlGaN/GaN high electron mobility transistor (HEMT). The class-F load network in microstrip topology was applied to a 0.75-m gate length and 300-m gate width AlGaN/ GaN HEMT. The 1 dB compression point o
