Product Description

UBS’ X-band solid state power amplifier (SSPA) is built using the latest GaN transistor technology. The highly-efficient design is the ideal replacement for TWTAs used in SATCOM applications. It offers 600 Watts of saturated power with maximum reliability and long service life.

The SSPA features monitoring and self-protection circuits including input overdrive, forward power, over temperature, operating current and operating voltage. Additionally, every GaN transistor if fully protected against potentially harmful reflected power caused by antenna mismatches.

The SSPA’s operational parameters are monitored and controlled by an integrated system controller. A front panel display provides the user with local monitoring and control, while Ethernet and RS485 interfaces provide the user with local/remote monitoring and control via PC GUI and Web GUI, SNMP optional.


The SSPA is a compact, 3RU, field replaceable system component, designed for rack mounting in a controlled indoor environment. It is force air cooled using integrated blowers and is powered by an external DC power supply. Optionally, the SSPA can be configured with an external 1RU L-Band to X-Band BUC and/or an external N+1 or N+2 1RU AC/DC power supply.
