Nisshinbo NJR2841 series Universal Ku-band 2LO PLL LNB - Mechanical Switch

Nisshinbo NJR2841 series Universal Ku-band 2LO PLL LNB - Mechanical Switch

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 switchable phase locked local oscillator from 9.75 GHz and 10.6 GHz frequency which is synchronized with either internal high stability TCXO reference or external 10MHz reference. The LNB receives an RF signal (Ku-band: 10.6 to 11.6 GHz and 11.6 to 12.75 GHz) as input, downconverts from the RF signal to an IF signal (L-band: 950 to 1,950 MHz and 1,100 to 2,150 MHz), and outputs the IF signal. The local frequency of switchable phase locked local oscillator is selected by three kind frequency band selections of “Outside Mechanical Switch”, “22kHz Tone On/Off”, and “Input Voltage High/Low” which are depended on model. 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.
