Product Description

Unique Broadband Systems’ DSPA4000KUB is an indoor 400W Solid State Power Amplifier (SSPA) built using GaN technology. This ultra compact 3RU amplifier is composed of two SSPA bricks, a forced air cooling system and a local front panel control with user friendly interface. In addition, the built-in system controller provides the ability of serial interfacing using RS 485, Ethernet and CAN-bus for remote monitoring and control as well as amplifier combining.

An internal voltage variable attenuator allows 15 dB of continuous gain adjustment. A digital temperature compensation system regulates the RF signal level within a +/-1.0 dB window over the entire operating temperature range. Rear access precision face-shifter is included for multiple amplifier combing. Every GaN output transistor is fully protected against potentially harmful reflected power due to antenna mismatches.

This amplifier is designed for rack mounting in protected environment. Excellent performance, high efficiency and long term MTBF are achieved through using superior mechanical and thermal designs. Our matured manufacturing process ensures the highest quality of all physical components and optimized performance to meet the most rigorous industry standards and clients’ demands. At the same time, our ISO 9001 Quality assurance program leads to the superior performance and reliability in the long-run.
