Ku-Band Dual Twts Pulsed Mpm For Space Application

The advances to MPM is introduced. A compact Microwave Power Module (MPM) for Space application is presented which consists of an electronic power conditioner (EPC), two solid-state power amplifiers (SSPA) and two short travelling wave tubes (TWT). The EPC and SSPA are assembled together with these two TWTs in one housing. The MPM weight less than 7kg is capable of providing output power over 500W with 45% efficiency in 15% duty cycle. The Phase Coherence of it is less than 5degree.
