Low-Ku-Band Intelligent Block Upconverter

The Terrasat Intelligent Block Upconverter (IBUC) offers integrated BUC/SSPA packaging for higher performance and reliability.

IBUC Advantages

Special low Ku frequency band supports 12.75 to 13.25 GHz band.

Low profile fan shroud on 12W and above.

DC power can be supplied via IFL coax or separate DC connector for 4W through 16W models.

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

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

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.

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

Advanced customer interfaces:
  • TCP/IP HTTP with embedded web pages.
  • SNMP
  • TELNET through TCP/IP
  • FSK through TX IFL cable.
  • RS232/485 serial port.
  • Handheld terminal.

1+1 switching logic built into IBUC eliminates expensive external controller.


Compared to traditional 70 MHz solutions, the IBUC offers significant benefits:

  • Lower terminal cost
  • Simpler 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 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
  • Alarm history

As always, the IBUC carries Terrasat's guarantee of rated output power across the operating band and specified temperature range. Unique in the IBUC are internal AGC and ALC functions to satisfy demanding applications with stringent specifications.

The IBUC is manufactured in a modern Morgan Hill, CA facility to the same exacting quality processes as the PowerPlus series and OEM microwave products. Each unit undergoes rigorous testing, burnin at elevated temperature, BER, and final testing over temperature so that you are assured of a high quality, reliable product.
