Terrasat Communications IBUC C-Band High Power Intelligent Block Upconverter (5.85 - 7.025 GHz) 100W - 200W
Freq. range 5.850 to 7.025 GHz in five sub-bands, IF 950 to 1450 Mhz, Interface CPR-137G, level stability with ALC +0.5 dB
IBUC C-Band Intelligent Block Upconverters (100W - 200W)
The Terrasat Communications IBUC C-Band High Power Series are highly advanced intelligent BUCs with special custom features such as low phase noise, built-in M&C and increased RF efficiency with Integrated fully automatic gain control and ALC.
The C-Band High Power IBUC also provides new interfaces for connecting you to extensive M&C facilities for etwork 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.
Guaranteed rated output power across the entire operating temperature range and frequency band. Low phase noise better than IESS308/309 requirements by a minimum of 5 dB.
Embedded Web pages provide management for small networks using any Web browser. AGC or ALC circuits hold gain
or output level constant. 16 dB 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
- Hand‐held terminal
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 C-Band High Power VSAT BUCs are internal AGC and ALC functions that satisfy demanding applications with stringent specifications.
