ERZ-LNB-3750-4250-50-3 Image

The ERZ-LNB-3750-4250-50-3 from ERZIA is a Low Noise Block (LNB) Downconverter that converts an input frequency (RF) from 37.5 – 42.5 GHz to an output frequency (IF) from 1.25 – 1.75 GHz. It provides a small signal gain of 55 dB and has a noise figure of 2.5 dB. This downconverter has undergone high reliability and dedicated screening procedures against standard military requirements. It requires a DC supply of 15 V and consumes 1 W of power. This downconverter is available in a module that measures 104.0 x 49.9 x 30.0 mm with a WR-22 waveguide input interface and SMA (female) output connector. It is ideal for SATCOM and aerospace applications.
