K-Band SSPA Technical Notes

This unit measures at 12.36” (L) x 8.57” (W) x 3.72” (H) (excluding DC connector), and weights 12.6 lb.  The unit operates on DC at 28 V, 14.2 A Max. The band of operation is 20.2 – 21.2 GHz. Its P1dB is 47 dBm or better across the band with a base temperature of 50°C. DC regulators shut down the unit if the SSPA temperature exceeds 55°C. Typical saturated power is 49 dBm with 5 dBm input power.

This K-Band SSPA needs cooling.  The standard amplifier package does not include a cold plate and chiller. Please contact for cooling requirements.
