Ku-Band BUCs Compact (25-40W)

The low cost Compact Ku-band BUC is built for VSAT stabilized platforms and mobile stations, while also offering benefits for fixed site and offshore applications. Weighing only 3.1kg (7lbs), makes it ideal for feed mounting.

Key Features

  • From 25 W to 40 W of available Power
  • 1:1 switching logic built into the BUC, eliminating expensive external controller (optional)
  • 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
  • IP65 rated housing and fan (weather proof construction)

 

Redundancy Manager

The 25 and 40W Compact 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:
