摘要

In this paper, basing on the radial-line waveguide combining technology, the W-band power amplifier is designed. The design of amplifier uses 4-way GaN MMIC combination. The output power is 3.7 W at 90 GHz and the combining efficiency is 94.3%. This structure has a good engineering application value.
