Spaceborne X-Band Solid State Power Amplifier
Highly Efficient and Reliable Power Amplifier and Power Converter
General Dynamics’ space-qualified, X-Band Solid State Power Amplifier (SSPA) operates over the frequency range of 7.8 to 8.8 GHz. The RF amplifier design is based on GaAs power MMIC technology providing high efficiency, high reliability, small size and low mass. Included in the unit is a DC-DC power converter and regulator, specifically designed for the SSPA utilizing synchronous rectifier technology to maximize power conversion efficiency. General Dynamics flight heritage includes both Mars Exploration Rovers and the Mars Curiosity rover. It will also be used on the Mars 2020 rover.
