Ku-Band 25W BUC SatPB-025Ku Series

The SatHarbor SatPB-025Ku Series is a high-performance 25 W Ku-Band Block Up Converter (BUC) that utilizes Gallium Nitride (GaN) power amplifier technology. It supports an RF output frequency range of 13.75 GHz to 14.5 GHz, delivering a typical output power of +44 dBm (25 W). Featuring approximately 70 dB of gain, low phase noise, and adjustable gain in 1 dB steps, this BUC is designed for stable satellite uplink transmissions. With RS-485 and Ethernet interfaces, IP65/IP67 enclosure options, and an operating temperature range from –25 °C to +60 °C, it is well suited for both fixed and mobile satellite communication environments.
