The GANSAT-400WKU is the highest-power model in the Gansat product line, delivering +56 dBm for large teleport hubs, high-power DTH broadcast uplink stations, and government/defense backbone links. Its GaN solid-state design provides maximum reliability for 24/7 operation.
The GANSAT-400WKU consumes 2000W of AC power for 400W of RF output — and compared to TWTA at the same power level, it offers instant startup, no cathode warm-up cycle, and longer MTBF. Its -40°C to +55°C operating range ensures reliable performance in harsh environments and critical applications.
A 400W Ku-Band GaN SSPA is used for maximum-EIRP satellite uplink: large teleport hubs, high-power DTH broadcast uplink, government/defense backbone links, and redundant hot-standby configurations. At +56 dBm, it provides the highest link margin in the Gansat SSPA product line.
The GANSAT-400WKU delivers 400W from 2000W AC. Compared to a TWTA at the same power level: instant startup, no cathode warm-up cycle, longer MTBF (no vacuum tube wear), and better spectral performance at back-off — all critical for 24/7 broadcast and teleport operations.
The Standard KU version covers 13.75–14.50 GHz; the Extended KU version covers 13.75–14.75 GHz. For high-power broadcast and teleport applications, the extended band is often required to reach all transponders on a given satellite arc.
