Abstract
An L-band 20% BW pulsed power amplifier that provides 1KW output power is presented. The amplifier circuit uses a combination of 500W NXP-LDMOS devices through the use of simple multi-section microstrip (Duroid 6006) hybrids. Instantaneous duty cycle is 1:10 with a maximum pulse duration of 1ms. This topology exhibits a transfer gain of 34dB, return losses better than 30dB along with an efficiency located in the range of 40%, which is suitable for SSPA-based Radar applications.
