Abstract:

This paper describes a Ku-band 80W solid-state power amplifier by using the waveguide bridge and waveguide-to-microstripe double probes transform structure.The waveguide bridge is used to improve the rejection rate between combination channels,and the waveguide-to-microstripe double probes transform structure can increases the integration of modules.Accordingly a higher power output is realized owing to the high dense integration.The pulse output power of this amplifier is 80W at 13.5~14.5 GHz with the corresponding power combining efficiency better than 81% and the power added efficiency greater than 25%.
