NJT8371 Series – Standard Ku-band 40W GaN BUC
A weatherized 40W GaN block up-converter for the standard 14.0-14.5 GHz Ku-band, with FSK monitor-and-control and MS-connector power feed.
The NJT8371 is a GaN-based Ku-band block up-converter for the standard 14.0 to 14.5 GHz band, delivering up to 40W (+46 dBm saturated output) from a 950-1,450 MHz IF input against a 13.05 GHz LO. It is built into a weatherproof, forced-air-cooled, IP67-rated enclosure and operates over -40 to +60C. Typical ACPR is -30 dBc at +44 dBm output, power draw is around 220W typical at +42 dBm output, and it runs on +36 to +60 VDC (with an AC power option). This NMK variant uses FSK monitor-and-control with MS-connector power supply; an RS-232C M&C option also exists in the series. It weighs 4.2 kg, includes an LED indicator, and is RoHS compliant. Note this is the standard-band counterpart to the universal-band NJT8371U series.
