The GANSAT-20WKU delivers 20W of Ku-Band RF power with GaN technology for the most demanding portable and mobile satellite uplink scenarios. At 4.7 kg with a wide-range DC input (36–65V), it operates from batteries or vehicle power — ideal for fly-away kits, SNG vehicles, and rapid deployment.

With low phase noise and IMD performance, the GANSAT-20WKU is well suited to commercial Ku-Band satellite uplink applications. Standard KU (13.75–14.50 GHz) and Extended KU (13.75–14.75 GHz) versions are available to match regional satellite access requirements.

Frequently Asked Questions

A 20W Ku-Band BUC is used for portable and mobile satellite uplink applications including fly-away kits, SNG vehicles, mobile VSAT terminals, and disaster recovery communications. It converts L-Band IF to Ku-Band RF for transmission to geostationary satellite transponders.

The GANSAT-20WKU weighs only 4.7 kg and accepts a wide-range DC input (+36V ~ +65V), allowing it to run from vehicle batteries or portable power sources for rapid field deployment. GaN technology optimizes the balance between RF output power and portability in a compact enclosure.

The Standard KU version (GANSAT-20WKU) covers 13.75–14.50 GHz, while the Extended KU version (GANSAT-20WEXTKU) extends to 13.75–14.75 GHz. The Extended KU band supports additional transponder capacity used by some satellite operators for regional coverage.
