Low-noise block downconverter - Wikipedia
A low-noise block downconverter (LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building.
LNB - 百度百科
LNB（low noise block downconverter）就是低讯降频放大器，它由LNB与LNC组成，LNC则由 混频器 、 本机振荡器 构成。 LNB一般可分为c频lnb（3.7GHz-4.2GHz）和ku频LNB（10.7GHz-12.75GHz）。 因卫星讯号在抵达天线前已相当微弱及 同轴电缆 传输的频率越高讯号损耗越大，所以才需要LNB来放大，同时还不能过多地恶化信噪比。 LNB的工作流程就是先将卫星高频讯号放大，再利用本地 振荡电路 将高频讯号转换至中频950MHz-2150MHz（依LNB种类决定中频范 …
Low Noise Block Downconverters (LNBs) - Orbital Research
Orbital Research builds high-performance, high-quality low noise block downconverters (LNBs) for the satellite communications industry. Our satellite LNBs are available for C, X, Ku and Ka-band. Each unit is expertly engineered, hand-tuned and tested, and comes with a datasheet that is unique to that individual LNB – actual measurements, not ...
Monoblock LNB - Wikipedia
Monoblock (or monobloc) low-noise block downconverters are a special type of LNBs representing a single device that contains several (typically 2–4) LNB units and a Digital Satellite Equipment Control (DiSEqC) switch. The latter allows the recipient to receive signals from several neighboring satellites each communicating different channels ...
Low Noise Block - an overview | ScienceDirect Topics
Low noise block application diagram with integrated downconverter. The RF signal received from the horizontal and vertical polarization feeds is amplified using a two-stage low noise amplifier (LNA). As one out of the two possible polarizations is received at a time in a single LNB, the second stage is common to both paths.
