NJT8319U Series – Universal Ku-band 16W BUC
A 16W Ku-band block up-converter for the universal 13.75-14.5 GHz band, supplied from the IF connector with no monitor-and-control interface on this base variant.
The NJT8319U block up-converter covers the universal Ku-band from 13.75 to 14.5 GHz and delivers up to 16W (+42 dBm P1dB), taking a 950-1,700 MHz IF input against a 12.8 GHz LO. It is built into a weatherized, forced-air-cooled enclosure rated IP67, with an extended operating guarantee up to +75 ℃ (performance guaranteed to +55 ℃). Typical ACPR is -28 dBc max at +41 dBm output, and power consumption at P1dB is about 160W typical from a +36 to +60 VDC supply (an AC power option is also available). This UN variant draws power directly from the IF connector and has no monitor-and-control interface; FSK and RS-232C M&C variants exist elsewhere in the series, some with MS-connector power. It weighs 2.4 kg, has an LED indicator, and is RoHS compliant.
