RF filters are passive or active components commonly used in the signal chain of virtually all radio and RF sensing technologies. The main purpose of a filter is to significantly attenuate unwanted portions of the spectrum, or specific frequencies, while only minimally impacting the operating frequencies. RF filters are typically constructed of various resonator technologies ..

RF filters are some of the most important components in receivers. The main functions of the filters are to reject undesirable signals outside the filter pass band and to separate signals according to their frequency. RF filters modify the amplitudes and phases of sinusoidal waveforms that pass through them or, more simply, RF filters remove unwanted ..
