Terrasat IBUC G Ka Band 80W AC-1

The Terrasat IBUC 2G series feature Gallium Nitride (GaN) amplifier technology. The key advantage of GaN is its high RF density and efficient power delivery. That is, the device delivers greater amplification in a smaller package. The IBUC G is cost-effective and reliable option for higher power requirements that will reduce the overall terminal cost. As a result, GaN-based IBUC G amplifiers are a viable alternative to TWTAs that can be easily deployed to support higher data rate applications including ad-hoc and full-time video services.

All Terrasat IBUCs are intelligent BUCs that communicate via FSK to compatible modems and provide alternate TCP/IP, RS232, and RS485 interfaces. Since it is SNMP-compatible, the IBUC easily integrates with your NMS so you have a complete view into all elements of your remote satellite terminals.

The IBUC also redefines protection switching with the logic and drivers built into the BUC. The need for a rack-mount remote control panel is entirely eliminated, saving cost and further simplifying installation.
