Ka波段25W固态功率合成放大器
25 W solid state power combining amplifier in Ka-band
摘要
Abstract
This paper presents a new waveguide-based spatial power combining amplifier at millimeter-wave frequency. In this amplifier, a waveguide-microstrip spatial power dividing/combining network is adopted. A four-way broadband low loss symmetrical power dividing/combining is achieved at millimeter-wave frequency with an easy manufacture processing and convenience of integrating solid-state high power devices. The measured output power of this amplifier is more than 43.4 dBm in 29 ~31 GHz, and the corresponding power combining efficiency is more than 80%. The obtained output power is more than 25 W in 30 -30.6 GHz.关键词
