Block Upconverter

300W High Power Ku Band Block Upconverter Module for Satellite Communication

ZD-BUC-13.75/14.5G-300W
This 300W High Power Ku-Band Block Upconverter (BUC) Module is designed for reliable satellite communication uplink applications. Operating at 13.75–14.5 GHz with a typical gain of 75 dB, it converts 950–1700 MHz IF signals to Ku-band RF output with high linearity and low phase noise. Built for harsh environments, the unit features IP66 waterproof rating and a wide operating temperature range of -40°C to +60°C, ensuring stable performance in outdoor and industrial conditions. With AC220V power supply, WR75 RF interface, and optional monitoring via RS232/485 or Ethernet, this compact 14.2kg module offers robust power efficiency and signal quality for VSAT, earth station, and remote communication systems.
