Nisshinbo NJS8486 series C-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 C-band. It is combined a 3-stage HEMT amplifier and a block downconverter with a phase locked local oscillator (5.15 GHz or 5.76 GHz) which is synchronized with internal high stability TCXO reference or external 10MHz reference. The LNB receives an RF signal (C-band: 3.4 to 4.2 GHz, 3.625 to 4.2 GHz, or 4.5 to 4.8 GHz) as input, downconverts from the RF signal to an IF signal (L-band: 950 to 1,750 MHz, 950 to 1,525 MHz, or 960 to 1,260 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 CPR-229G waveguide flange as RF input and an either an N-type or F-type female connector as IF output.
