摘要: A high efficiency power combining demonstration is presented in this paper of 2 X-band TWTAs based on magic-T corporate combiner. low loss, amplitude and phase balanced, isolation waveguide combiner designed. Power efficiencies greater than 90% output more 85W over a 0.7GHz frequency band are successfully demonstrated by introducing shifter variable attenuator within input end. Such can also be taken as an element architecture for much outputting satellite communication.
