Ku-Band BUC’s (50-250W)

Ideal solution for both mobile and fixed communication terminals. Designed for high efficiency, resulting in an optimal compact form factor with high performance and reliability. With the advanced customer interface and HTTP embedded web page, the operator is able to monitor and control both BUC and the system redundancy.

Key Features

  • DUAL LO = same unit covers both standard and extended Ku-Band
  • Extremely compact size
  • 1:1 switching logic built into the BUC, eliminating expensive external controller
  • Built-in telemetry facilities for critical parameters such as: RF power detection, mute control, over temperature shutdown, summary alarm
  • WEB interface and SNMP monitoring
  • RS485, RS232, Ethernet and dry-contacts M&C Interface

 

Redundancy Manager

The 50-250W Ku-Band BUC’s integrate fully with IGP’s advanced content based Redundancy Manager. This Redundancy Manager uses site diversity software with intelligent switching (within one second to an optional amplifier) based on source comparison and multiple receiver info:
