摘要
介绍了一种新型的毫米波波导空间固态高功率合成放大器.该放大器中采用的波导-微带空间功率合成网络,在毫米波频段实现了幅度、相位对称的四路功率分配/合成和波导-微带过渡转换,由此研制的毫米波高功率合成放大器,在29～31 GHz范围内,合成效率高于80%,输出功率大于43.4 dBm,并在30～30.6 GHz内高于25 W.
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.
