Terrasat IBUC G Series 400W X-Band GaN Intelligent Block Upconverter (7.9 - 8.4 GHz)
Freq. range 7.90 to 8.40 GHz, IF 950 to 1450 Mhz, Input Connector Type-N, RF Output Interface CPR-112G
IBUC G Series 400W X-Band Intelligent Block Upconverter
The Terrasat IBUC G Series 400W X-Band GaN is a revolutionary Block Upconverter with advanced features such as a Gallium Nitride amplifier for increased efficiency. Integrated fully automatic gain control and ALC comes standard on all BUCs with all second generation GaN BUCs.
The X-Band 400W IBUC G Series also provides new interfaces for connecting you to extensive M&C facilities for network management or local access. This powerful M&C enables trouble‐free commissioning with easy, point‐and‐click installation/configuration, continuous verification of performance with time‐stamped alarm history and simplified monitoring of terminal status.
IBUC-G 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-G are internal AGC and ALC functions that satisfy demanding applications with stringent specifications.
