Abstract

In this paper, a W-band four-way power divider/ combiner using waveguide rat-race hybrid and double-probe waveguide-to-microstrip transition is proposed. This divider/ combiner has properties of low loss, equal power splitting, compact structure, good return loss, and good heat dissipation. The 3D EM simulation results show that, from 90GHz to 100GHz, the return loss is better than 20dB and the insertion loss is less than 0.3 dB. Integrated with MMIC power amplifiers, the divider/combiner can be used in power combing systems to obtain solid-state high power with a high efficiency in W-band.
