Nisshinbo NJT8334 series Standard Ku-band GaN 8W BUC

Description

NJT8334 is a Ku-band block up-converter of 14 to 14.5 GHz and transmits the amplified RF signals of up to 8W (+39 dBm) of linear output power, in an ultra-compact weatherproof enclosure with forced air cooling.

The NJT8334 is designed for the block up-converter intended for the satellite communication data uplink application in Ku-band. It can transmit an RF signal (Ku-band: 14.0 to 14.5 GHz or 13.75 to 14.5 GHz) output with up to 8W (+39 dBm) linear operation. It is combined a high power GaN HEMT and linearizer for higher power linear output, and a block up-converter with a phase locked local oscillator (13.05 GHz or 12.8 GHz) which is synchronized with external 10MHz reference.
The BUC receives a reference signal (10 MHz) and an IF signal (L‐band: 950 to1,450 MHz or 950 to 1,700 MHz) input and transmits an RF signal (Ku-band: 14.0 to 14.5 GHz or 13.75 to 14.5 GHz) output.

It is operated by +24 V / +48 V DC power (Range: +18 to +54 V) input via either Circular Connector or IF Connector. The BUC can support the monitor and control functions by either Ethernet interface with both HTTP protocol of web browser and SNMP v2c protocol or RS-485 (or RS-232C option) interface with NISD original protocol. The BUC comes in a single, weatherized housing rated for outdoor use and has either an N-Type or F-type female connector as IF input, a WR-75 waveguide flange as RF output.
