What does a low pass filter do? A low pass filter passes all frequencies below its cutoff frequency and attenuates all frequencies above it. This filter is designed to attenuate harmonics produced by RF amplifiers. For example, if an RF amplifier is operating at 100MHz it will produce a carrier at 200MHz, 300MHz etc. These carriers can interfere with other radio services and they can attract regulatory agencies to your door step. Low pass filters will not eliminate in band spurs.
