C-Band IBUC Intelligent Block Upconverters 5-80W

The revolutionary Terrasat IBUC has advanced features to take your network to new heights

IBUC Advantages

Integrated BUC/SSPA for higher performance and reliability.

DC power can be supplied via IFL coax or separate DC connector for 5W through 25 W models.

All models available with integral AC power supply or separate DC power supply.

Internal 10MHz reference option automatically switches to internal reference when external reference is not available.

Guaranteed rated output power across the entire operating temperature range and frequency

Low phase noise exceeds IESS308/309 requirements by a minimum of 10 dB.

Embedded web pages provide management for small networks using any web browser.

AGC or ALC circuits hold gain or output level constant.

16dB User-adjustable gain in 0.1 dB steps preserves modem dynamic range.

Advanced user interfaces:
TCP/IP HTTP with embedded web pages.

  • SNMP
  • TELNET through TCP/IP
  • FSK through TX IFL cable.
  • RS232/485 serial port.
  • Handheld terminal.

IBUC offers significant benefits:

  • Low terminal cost
  • Simple design and installation
  • Superior RF performance
  • Simplified 1+1 configuration

New interfaces connect you to the IBUC’s extensive M&C facilities for network management or local access. This powerful new M&C enables:

  • Trouble free commissioning with easy, point-and-click installation/ configuration
  • Continuous verification of performance with time-stamped alarm history.
  • Simplified troubleshooting of terminal faults.

The IBUC comes with a complete set of diagnostic tools including:

  • 10 MHz input detector
  • Input voltage and current monitoring
  • Transmit L-band input level detector
  • Transmit RF output level detector
  • User configurable thresholds and alarms

Unique to the IBUC are internal AGC and ALC functions that satisfy demanding applications with stringent specifications.
