Nisshinbo NJT8319UNK

Nisshinbo NJT8319UNK Ku-band 13.75 - 14.5 GHz 16W BUC

The NJT8319UNK is a compact and high-performance Ku-band 16W BUC (Block Upconverter) designed for VSAT uplink applications. It operates over 13.75–14.5 GHz (universal Ku-band) with a 12.8 GHz local oscillator, converting L-band IF signals (950–1700 MHz) to RF for reliable satellite transmission. With P1dB +42 dBm output power, stable gain, and support for external 10 MHz reference, it ensures consistent uplink performance in broadband and enterprise satellite systems.
