200W POWER AMPLIFIER FOR PULSED RADAR USING GaN FET

摘要

A 200W power amplifier for a pulsed radar using a GaN FET is provided. A power amplifier according to an embodiment of the present invention includes a distribution circuit for input signal divergence, an amplification circuit for amplifying the diverged input signal by using GaN FETs and a coupling circuit coupling amplified input signals in the amplification circuit. Thus, the efficiency of the amplifier can be improved by applying a GaN semiconductor device which is easy to achieve high frequency, high output, and high efficiency.;COPYRIGHT KIPO 2017
