High power and efficiency power combining with multi-way TWTAs for satellite communications
A high efficiency power combining demonstration is presented in this paper of 4 K-band TWTAs based on magic-T corporate combiners. A low loss, amplitude and phase balanced, high power corporate magic-T combiner is designed. Power combining efficiencies of greater than 90% and output power of more than 340W over a 0.6 GHz frequency band are successfully demonstrated. Such hybrid junctions can also be considered as elements within a corporate combining architecture for much higher power generating for satellite communications or other industrial applications.
