A low-pass filter is a device that allows signals with low frequencies to pass through while blocking or attenuating signals with high frequencies. People often use low-pass filters in wireless video transmitters to reduce interference from harmonics and other noise sources. They can also protect GPS and radio signals from being affected by the transmitter’s output power.
Different types of low-pass filters exist, such as ceramic, multilayer, electromechanical, and SAW filters. Each type has its advantages and disadvantages, depending on the application and the frequency range. When choosing a low-pass filter, some factors are insertion loss, Dämpfung, bandwidth, impedance, and size.
