Nisshinbo NJR2837 series Ku-band PLL LNB - Int. Ref.

Scope

This LNB is designed for the low noise amplifier and block downconverter intended for the satellite communication data downlink application in Ku-band. It is combined a 3-stage HEMT amplifier and a block downconverter with a phase locked local oscillator (10 GHz, 10.25 GHz, 10.75 GHz or 11.3 GHz) which is synchronized with internal high stability TCXO reference. The LNB receives an RF signal (Ku-band: frequency divided by region band from the 10.75 to 12.75 GHz) as input, downconverts from the RF signal to an IF signal (L-band: 950 to 1,700 MHz), and outputs the IF signal. It is operated by +24 V DC power (range: +12 to +24 V) input. The LNB comes in a single, weatherized housing rated for outdoor use, and has a WR-75 waveguide flange with groove as RF input and an either an N-type or F-type female connector as IF output.
