NJR2843 Series – Universal Ku-band 2LO PLL LNB (Input Voltage High/Low)
A Universal Ku-band LNB that selects its local oscillator band via a high/low input voltage signal.
The NJR2843 series is a low-noise block downconverter covering the Universal Ku-band (10.7 to 12.75 GHz), where the local oscillator band is selected by switching the supply voltage between high and low. As with the rest of the NJR284x family, it covers the L-band and H-band frequency plan with a typical 0.8 dB noise figure. It’s available in multiple internal-reference stability grades plus an external-reference option, in both F-type and N-type connector variants. RoHS compliant.
