Our UniMatrix family of X-Band solid state power amplifier (SSPA) systems are built using the latest GaN transistor technology. The highly efficient designs are the ideal replacement for TWTAs used in SATCOM applications. They offer up to 6.6kW of saturated power with maximum reliability and long service life.

 

The modular design includes a BUC (optional), pre-driver, SSPA modules, arc detection system, passive combining/switching network and system controller. A power supply system with PDU and hot-swappable AC/DC power supplies is also included.The scalable systems can be customized to operate with 4, 8 or 16 phase combined SSPA modules, and can be updated in thefield as output power requirements change.The systems can be configured to operate in the standard 1+1 combined mode or optional 1:1 redundant mode. Passive combing is employed to avoid interruptions in the RF output power, while an integrated linearizer ensures the systems operate at maximum power without seeing a degradation in intermoduation performance. The AGC circuit maintains a constant gain value, with +0.25 dB accuracy over the life of the system; an ALC circuit with constant output power level is optional. Additionally, the systems are equipped with an arc detection system, which will detect and rapidly shut down the system when an arc occurs.

 

The UniMatrix systems also feature a number of monitoring and self-protection circuits including input overdrive, forward power, reflected power and over temperature. The system controller provides a user friendly interface for monitoring and control of the complete UniMatrix system as well as the individual SSPA modules. 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.
