Indoor X-Band 1.86-6.6KW GAN SSPA System

Product Description:


DVB-Tech X-Band solid state power amplifier (SSPA) system is built using the latest GaN transistors technology. The highly  efficient design is the ideal replacement for TWT amplifiers used in SATCOM applications. It offers 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 the field as output power requirments change. The system can be configured to operate in standard 1+1combined mode or optional 1:1 redundant mode.  Passive combing is employed to avoid interruptions in the RF output power, while an ALC circuit maintains a constant output power level, with +0.25 dB accuracy, over the life of the system.  The integrated linearizer ensures the systems operate at maximum power without seeing a degradation in intermoduation performance.


The UniMatrix systems also feature a number of monitoring and self-protection circuits including input overdrive, forward power, reflected power and over temperature. Additionally, the systems are equipped with an arc detection system which will detect and rapidly shut down the system when an arc occurs.

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.
