Abstract
A 1.6 W power amplifier module was developed at 24 GHz using a novel waveguide-based power combiner. The combiner is based on a double antipodal finline-to-microstrip transition structure which also serves as a two-way power combiner. Back-to-back connected combiner showed insertion losses less than 0.6 dB and return losses better than 17 dB over most of the Ka-band. The power combiner was employed to combine the output powers of two 1 W MMIC PA's. The power module showed 32.2 dBm output power including the loss of transition and a combining efficiency of 83%.
