This C-band LNB 4.75–5.3 GHz WR-159 N/F/SMA is a high-efficiency frequency downconverter designed for modern satellite reception, microwave links, and broadband signal transport systems. Operating in the 4.75–5.3 GHz input range and converting to a 0.95–1.5 GHz IF output, it features a highly stable 3.8 GHz local oscillator with ±1 ppm frequency stability and superior phase noise characteristics (–95 dBc/Hz @ 1 kHz).
The low-noise figure (1.9 dB max), high gain (49 dB min), and integrated automatic gain control (AGC) system with 25 dB depth ensure robust signal integrity even in challenging environments. Flatness over the full band is kept within ±3.3 dB, while mirror channel suppression is at least 45 dB.
L.O.: 3.8 GHz IN freq.: 4.75–5.3 GHz OUT freq.: 950 – 1500 MHz
The unit features WR-159 waveguide input and flexible output options including N-type, F-type, and SMA connectors, making it compatible with a wide range of professional RF setups. This LNB is suitable for TV broadcast operators, telecom service providers, research labs, and RF system integrators.
