What is low noise amplifier?
Aug , 24 2024
Low-noise amplifier/LNA is a special kind of electronic amplifier, which is mainly used to amplify the signal received from the antenna in communication system, so as to facilitate the processing of electronic equipment in the later stage. Because the signal from the antenna is generally very weak, low noise amplifiers are generally located very close to the antenna to reduce the loss of the signa...
