This paper presents the development of a E-Band 7186 GHz solid state high power amplifier SSPA for nanosatellite applications. A suspended stripline to WR-10 waveguide transition is utilized. The microwave module utilizes a commercial MMIC that operates from 76-86 GHz with a Psat of 25 dBm. 4 MMICs are power combined using WR-10 waveguide, and the power combined module has a measured bandwidth equal to the full band of the MMIC and is capable of outputting over 0.5W at 85 GHz. Simulations show an efficiency of 86 for the 4-way combiner. The developed HPA is a critical block for future millimeter-wave Nanosatellite communication links.
