About
The SSPA11201721SS is a high-power integrated K-band solid state power amplifier module fabricated on space-qualified GaN on SiC technology, operating from 17-20.5 GHz and delivering over 10 W (>40 dBm) of saturated output power across the entire band. The module integrates the full SSPA chain including GaN MMIC die, bias circuits, and RF matching networks in a compact 63x60x25 mm aluminum housing.
Biased from a single 25-28 VDC supply and activated through an enable signal, the module features integrated power detection and temperature monitoring to facilitate system health telemetry and gain control. The VSWR is 1.90:1, and RF ports use 2.92 mm connectors for compatibility with K-band waveguide and coaxial test equipment.
The SSPA11201721SS is designed for demanding SATCOM downlink amplification tasks, Ka-band satellite ground terminals, and point-to-point wireless links requiring high power density and reliable performance. Its compact, fully integrated design significantly reduces system integration effort compared to discrete GaN die implementations, while the on-board monitoring functions enable autonomous system management in satellite payloads and remote ground terminals.
