Terrasat iBUC 3G Ku-band

Terrasat IBUC 3G Ku-Band GaN BUC (25W–40W)

Compact High-Efficiency GaN Ku-Band Block Upconverter for Multi-Carrier Mobility Applications

The Terrasat IBUC 3G Ku-Band is a compact, high-efficiency GaN-based intelligent block upconverter designed for demanding multi-carrier uplinks in mobility and small-antenna SATCOM systems. Available in 25W, 30W, and 40W output levels, the IBUC 3G delivers higher power in a small, lightweight enclosure using advanced Gallium Nitride (GaN) amplifier technology.

Engineered for mobility platforms, flat-panel antennas, transportable terminals, and compact VSAT systems, the IBUC 3G combines strong linear performance, reduced power consumption, and full-feature intelligent monitoring.

Esatcom Inc. supplies factory-configured IBUC 3G units tailored to your frequency plan, reference stability, and network requirements.
