Aethercomm Model Number SSPA 7.5-10.0-1000 is a space qualified, Gallium Nitride (GaN) LEO solid state power amplifier that operates from 7.5-10.0 GHz. It is packaged in an enclosure that is optimized for high altitude operation along with high performance shock and vibration to include LEO flight. Nominal output power is 1000 watts minimum. The composite power added efficiency with a pulsed RF input is 25-30% at Pout max. Input VSWR is 1.5:1 typical and output VSWR is 2.0:1 typical. This SSPA can be blanked on and off in less than 2.0 uSec. Standard features include reverse polarity protection, output short and open circuit protection, and over/under voltage protection. Temperature is monitored and reported by this module along with many other health parameters. This power amplifier module operates from –40°C to +85°C base plate temperature.
This high power SSPA, is employed on a space based sensor. It is designed for a five year mission life. It is capable of all the shock and vibration requirements to lift and survive in space. The housing volume is approximately 4.6” (w) x 10.9” (I) x 2.0” (h) with a step for the output waveguide flange of 3.0”. DC and logic connections are accessible via DSUB connectors. The RF input connector is an SMA female. The RF output connector is WR-90 waveguide. Typical transmit test data appears on page two of this data sheet at room temperature.
