| 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 and 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 43.4dBm in 29-31, and the corresponding power combining efficiency is more than 80%. The obtained output power is more than 25W in 30-30.6GHz. |
