Abstract
High power amplifier is the key element of microwave transmitters. Solid-state spatial power combiner is issued to replace traveling wave tube amplifier (TWTA) in space communication systems. To comply with space requirements a new compact Ka-band spatial power combining architecture is proposed using a double-faced tray. To match the 2 times 2 combining structure, double antipodal finline is designed to achieve power distributing/combining and transition between waveguide and microstrip. A 29~30 GHz spatial power combiner is designed following this architecture. With it the compact architecture proves effective and prospective.
