The X-band LNB 7.7–8.25 GHz WR-112 N/F/SMA is engineered for high-precision RF applications such as radar, telemetry, and X-band satellite ground stations. It downconverts signals in the 7.7–8.25 GHz band to a 950–1500 MHz intermediate frequency, using a 6.75 GHz PLL-stabilized local oscillator with ±5/10/25 kHz LO stability.

Designed with a WR-112 waveguide flange (with groove), the LNB provides outstanding performance in real-world environments. Its typical 0.6 dB noise figure, 60 dB gain, and excellent phase noise characteristics make it a trusted solution for demanding applications. The LNB comes in a compact, IP67-rated waterproof housing, and supports +12 to +24 VDC power input.
