Compact Ka Band LNB 18.2‑21.7GHz Small Size Satellite Low Noise Block

This lightweight, space‑saving Ka band LNB serves as a high‑performance low noise block and compact satcom LNB tailored for portable and transportable satellite communication deployments. Covering 18.2‑21.7 GHz frequency range, it supports single‑band and voltage‑switched dual‑band modes, with PLL‑driven ±1 ppm internal LO stability and optional external reference input for high‑accuracy system requirements. This Ka band LNB delivers 1.5 dB to 1.6 dB noise figure depending on selected bands, alongside adjustable conversion gain of 55‑65 dB. As a robust low noise block, it features minimum 10 dBm output P‑1 (15 dBm typical), low phase‑noise surpassing IESS308/309 specifications, and linearity optimized for high‑order modulation and high‑data‑rate transmission. Weighing merely 190‑210 g, this satcom LNB is IP65‑protected, operating steadily across ‑40℃ to +60℃ in condensing‑humidity conditions. It consumes 5 W powered by 12‑24 VDC over IF line, fitted with WR42 grooved input and selectable F‑type / N‑type female output connectors, perfectly suited for maritime, SNG vehicle, fixed and mobile VSAT terminal applications.
