Abstract

A V-band high-efficiency power-combining module was developed using double antipodal finline structures. The combiner performs the dual functionality of power combining and mode transition from microstrip to waveguide. The measurement of the back-to-back connected combiner demonstrated an insertion loss of 1.2 dB and return loss better than 15 dB around 60 GHz with a 3 dB bandwidth of 18 GHz. The power-combining module incorporating two MMIC power amplifiers demonstrated a combining efficiency higher than 80%.
