Nisshinbo NJT8315LN

Nisshinbo NJT8315LN Ku-band 12.75 - 13.25 GHz 2W BUC 

The NJT8315LN is a compact and high-performance Ku-band 2W BUC (Block Upconverter) designed for VSAT uplink applications. It operates over 12.75–13.25 GHz (Lower Ku-band) with a 11.8 GHz local oscillator, converting L-band IF signals (950–1450 MHz) to RF for reliable satellite transmission. With +33 dBm output power, stable gain, and support for external 10 MHz reference, it ensures consistent uplink performance in broadband and enterprise satellite systems.
