NJT8371U Series – Universal Ku-band 40W GaN BUC
A weatherized 40W GaN block up-converter covering the full 13.75-14.5 GHz universal Ku-band with FSK monitor-and-control and MS-connector power feed.
The NJT8371U is a Ku-band block up-converter built around a GaN power amplifier, designed for the universal 13.75 to 14.5 GHz band and capable of delivering up to 40W (+46 dBm saturated output). It accepts a 950-1,700 MHz IF input against a 12.8 GHz LO, and is housed in a weatherproof, forced-air-cooled enclosure rated IP67 for outdoor use. Key characteristics include an ACPR of -30 dBc typical at +44 dBm output, DC power input of +36 to +60 VDC (with an AC power option), and FSK-based monitor-and-control on this NMK variant (an RS-232C M&C option also exists elsewhere in the series). The unit weighs 4.2 kg, includes an LED status indicator, and is RoHS compliant.
