Nisshinbo NJR2845A 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 2-stage HEMT amplifier and a block downconverter with a phase locked local oscillator (10 GHz, 10.25 GHz, 10.75 GHz, 11.25 GHz, or 11.3 GHz) which is synchronized with either internal high stability TCXO reference or external 10MHz 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: +10 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.
