This contribution presents the development and the experimental results of a spaceborne VHF high-power Solid-State Power Amplifier (SSPA) based on European Gallium Nitride technology, suitable for integration in future Earth observation subsurface radar instrument. The developed high-power section of the overall SSPA delivers an output power exceeding 800 W with an associated gain and power added efficiency of about 21 dB and 70 %, respectively, from 40 to 50 MHz.

Abstract
This contribution presents the development and the experimental results of a spaceborne VHF high-power Solid-State Power Amplifier (SSPA) based on European Gallium Nitride technology, suitable for integration in future Earth observation subsurface radar instrument. The developed high-power section of the overall SSPA delivers an output power exceeding 800 W with an associated gain and power added efficiency of about 21 dB and 70 %, respectively, from 40 to 50 MHz.File in questo prodotto:
