A Four-Way High-Power Combiner Employing Hybrid Microstrip and Waveguide Structure

This paper presents an X-band four-way high-power combiner employing hybrid microstrip and waveguide structure. To satisfy the requirement of compact configuration and high power capacity, the power combiner adopts a four-way hybrid microstrip and waveguide architecture. The input network adopts the microstrip prototype and the output network utilizes waveguide structure. To verify the design concept, the proposed configuration is designed, fabricated, and measured. The experimental outcomes indicate that the proposed power combiner achieves a bandwidth of 9.2 to 10.8 GHz with a minimum insertion loss of 1.52 dB.
