WebA Bandpass Filter (BPF) is a 2-port Radio Frequency (RF) filter component which is used in a RF signal path to pass a specific range of frequencies and to suppress (attenuate) the frequencies on either side outside of that range. The most demanding BPFs are used in the RF front-end of Time Division Duplexed (TDD) systems at the antenna port. http://www.w7ekb.com/glowbugs/ModsEtc/modifications.htm
