Low Noise Amplifier (LNA) and Filter can improve system performance and anti-interference ability through signal enhancement and noise reduction, signal filtering and spectrum shaping in satellite communications.
1. At the receiving end of satellite communications, LNA is mainly used to amplify weak signals. At the same time, LNAs also need to have low noise characteristics to avoid amplifying the noise together, which can affect the signal-to-noise ratio of the entire system.
2. Filters can be used in satellite communications to suppress interfering signals and select the frequency band of the desired signal.
3. The band-pass filter can filter out the signal in the specified frequency band and use it to select the desired frequency band for channel communication.
