Our C‑band LNB 4.75–5.3 GHz WR‑159 converter is expertly designed to amplify weak satellite and telecom signals in the 4.75–5.3 GHz range and down-convert them to 0.95–1.5 GHz. Featuring a low noise figure, high-stability heterodyne, efficient AGC system, and wide dynamic range, it ensures pristine signal integrity. The hermetically sealed metal housing offers superior protection against dust and moisture, and is engineered for mounting at the focus of parabolic antennas. Inputs via WR‑159 waveguide and N‑type output—powered remotely through coaxial cable. Ideal for companies, TV providers, and professional developers seeking robust, lab-tested telecom equipment.
