10.7‑12.75GHz Ku Band LNB Low Noise Block
ZD-LNB-10.7/12.75G
This 10.7‑12.75GHz Ku‑Band LNB low noise block features PLL‑controlled local oscillator with ±3 ppm stability and typical 0.8 dB noise figure, max 1.0 dB. It supports single‑band and dual‑band operation, with dual‑band switchable via DC voltage or 22 KHz tone. Delivering 60 dB conversion gain and minimum 5 dBm output P1dB, it ensures excellent phase‑noise and low spurious performance. Built for harsh outdoor conditions, it operates from ‑40℃ to +60℃ with IP65 waterproof rating, tolerates 0‑100% condensing humidity. Powered by 12‑24 VDC via IF line with 3 W power consumption. Equipped with WR75‑G input connector and optional F‑type / N‑type female output interface. Ideal for maritime, SNG vehicles, VSAT fixed, portable & transportable terminals as well as 5G backhaul satellite communications

This high‑performance Ku‑Band LNB, also known as a low noise block, is a robust Satcom LNB engineered for professional satellite communication systems. It covers 10.7‑12.75 GHz RF input frequency, supporting both single‑band and dual‑band modes. The dual‑band function can be switched by DC voltage or 22 KHz tone signal to meet different satellite receiving requirements. Adopting advanced PLL local oscillator design, it delivers ±3 ppm LO stability, typical 0.8 dB noise figure (max 1.0 dB), 60 dB conversion gain and excellent phase‑noise performance. With 5 dBm minimum output P1dB and controlled spurious output, this Ku‑Band LNB guarantees stable signal reception in complex RF environments. Built to IP65 waterproof standard, the low noise block works reliably under ‑40℃ to +60℃ wide temperature range and 0‑100% condensing humidity. It accepts 12‑24 VDC power supply via IF line with 3 W power draw, fitted with WR75‑G input connector and optional F‑type / N‑type female output ports. As a versatile Satcom LNB, it fits maritime, SNG vehicles, fixed, portable & transportable VSAT terminals and 5G backhaul applications.
