Ka-band LNB 20.2-21.2 GHz WR-42 N/F/SMA

The Ka-band LNB 20.2–21.2 GHz WR-42 N/F/SMA is a professional-grade low-noise block downconverter designed for satellite communication, RF testing, and telecommunication systems. Engineered with a WR-42 waveguide flange, this unit supports input signals in the 20.2 to 21.2 GHz range and downconverts them to a 0.95–1.95 GHz IF output, making it highly suitable for receivers and signal analyzers. Its integrated local oscillator (LO) at 19.25 GHz ensures frequency stability for precision applications.

With N-type, F-type, and SMA output connectors, this LNB offers compatibility across diverse setups. The low noise figure, enhanced dynamic range, and solid thermal stability make it a go-to solution for broadcasters, test engineers, military-grade communications, and scientific research labs.
