SSPA – Definition and Pronunciation
What is SSPA?
SSPA is HPA using solid-state technology (i. e., transistors). Originally used for low and medium power applications; however reliable medium-power to high-power SSPA technology has emerged and is used routinely at earth stations and on spacecraft.
Examples of SSPA
PA (power amplifiers), specifically high-power amplifiers (HPAs), for example, solid state power amplifier (SSPA) or a klyston. Transmit power amplifiers provide amplification of signals to be transmitted to the satellite (typically 750–3 000 W).

The BUC is typically 5 W RF (+37 dBm; 88 W input power) or 10 W RF (+40 dBm; 170 W input power) (SSPA and upconverter), to upconvert L-band IF signal to Ka-band RF signal (27,652–29,071 GHz), more specifically, operation at 27,652–28,388 GHz with 26,600 GHz LO and 28,172–29,071 GHz with 27,200 GHz LO.
From “High Throughput Satellites (HTS) and KA/KU Spot Beam Technologies”.
