Abstract:In this paper, basing on the radial-line w aveguide combining technology, the W-band pow er amplifier is designed. The design of amplifier uses 4-w ay Ga N M M IC combination. The output pow er is 3. 7 W at 90 GHz and the combining efficiency is 94. 3%. This structure has a good engineering application value.
