An engineering model (EM) of 1 kW class X band high power pulsed amplifier (XPA) for Synthetic Aperture Radar (SAR) system that aims to install in a 100 kg class small satellite was developed. We performed verification tests and evaluated resistance against launch conditions and space environments of the XPA. In this paper, we describe a concept of the XPA and results of the verifications tests.
