10.7-12.75GHz Ku-band Low Noise Block

This Ku‑Band 10.7‑12.75GHz LNB low‑noise block supports single‑band and dual‑band modes. It delivers typical 0.8 dB noise figure (max.1.0 dB) with ±3ppm LO stability. Band switching is available via voltage or optional 22KHz tone. With IP65 rating and DC power feed, this compact unit applies to Ku‑band satellite receiving systems.

Product Detail

This Ku‑Band 10.7‑12.75 GHz low‑noise block (LNB) supports single‑band and dual‑band operation modes. Single‑band configurations offer RF input of 10.95‑11.70 GHz and 11.70‑12.20 GHz, while dual‑band covers 10.70‑11.70 GHz and 11.70‑12.75 GHz. Corresponding IF outputs are 950‑1700/950‑1450 MHz or 950‑1950 MHz & 1100‑2150 MHz. It achieves typical 0.8 dB noise figure (max. 1.0 dB), ±3 ppm LO stability, 60 dB conversion gain and minimum 5 dBm output P1dB. LO leakage is limited to max.‑30dBm at IF port and max.‑60dBm at RF port.

Powered by 12‑24 VDC over coaxial cable with 3 W power consumption. Band switching is realized by voltage level, with optional 22 KHz tone control. RF input adopts WR75‑G grooved waveguide; output is standard F‑type female with N‑type female as option. Measuring 94×40×40 mm and weighing 240 g, it features IP65 waterproof rating. Operating from ‑40℃ to +60℃ under condensing humidity conditions, it is widely used in various Ku‑band satellite receiving terminals.
