The GANSAT-50WKU delivers 50W of GaN RF output power for fixed and semi-permanent satellite uplink stations, providing high EIRP margin for reliable throughput. With 220V AC power and 8 kg weight, it suits both ground station configurations and straightforward field installations.

Low phase noise and IMD performance make it well suited to commercial Ku-Band satellite uplink applications. Thanks to GaN technology, the unit consumes only 240W of AC power — significantly more efficient than equivalent TWTA solutions.

Frequently Asked Questions

A 50W Ku-Band BUC is used for VSAT hub stations, teleport ground stations, and broadcast contribution links. It provides higher EIRP margin than lower-power units, enabling reliable throughput even on smaller antennas.

GaN solid-state amplifiers require no vacuum tubes, start instantly with no warm-up, offer lower phase noise, and provide better linearity at back-off. The GANSAT-50WKU consumes only 240W for 50W of RF output — significantly more efficient than equivalent TWTA solutions.

The Standard KU version (GANSAT-50WKU) covers 13.75–14.50 GHz, while the Extended KU version (GANSAT-50WEXTKU) covers 13.75–14.75 GHz. The extended band is required for operators accessing satellites that use the full Ku uplink allocation.
