Nisshinbo NJT8318NK

Nisshinbo NJT8318NK Ku-band 14.0 - 14.5 GHz 8W BUC

The NJT8318NK is a compact and high-performance Ku-band 8W BUC (Block Upconverter) designed for VSAT uplink applications. It operates over 14.0–14.5 GHz (universal Ku-band) with a 13.05 GHz local oscillator, converting L-band IF signals (950–1450 MHz) to RF for reliable satellite transmission. With P1dB +39 dBm output power, stable gain, and support for external 10 MHz reference, it ensures consistent uplink performance in broadband and enterprise satellite systems.
