The Ka-band LNB 22.2-23.2 GHz WR-42 N/F/SMA is a high-performance low-noise block downconverter engineered for demanding satellite, RF, and telecom applications. It receives signals in the 22.2-23.2 GHz Ka-band and converts them to an output range of 1.0-2.0 GHz, allowing for easy integration with lower-frequency receiver systems. Built with a high-stability 21.2 GHz LO and low phase noise, this Ka-band LNB is engineered to minimize signal degradation and maximize performance in demanding environments. The compact design makes it ideal for remote deployments.
