KU250 250W Ku Band BUC Block Upconverter for Satellite Communication
The KU250 is a high-power 250W Ku-band block upconverter designed for professional satellite communication earth stations and outdoor ground terminals. Based on advanced GaN technology, it combines efficient RF power amplification, stable frequency conversion and reliable protection functions in a compact enclosure.
Product Overview
The BUC converts the L-band intermediate-frequency signal to the Ku-band transmit frequency range of 13.75-14.5 GHz. It supports a 10 MHz reference input through the IF port, provides high small-signal gain and allows 20 dB gain adjustment in 0.5 dB steps. The 250W rated output is suitable for high-throughput satellite links, fixed satellite terminals, communication gateways and demanding outdoor RF systems.
