A crystal filter allows some frequencies to 'pass' through an electrical circuit while attenuating undesired frequencies. An electronic filter can use quartz crystals as resonator components of a filter circuit. Quartz crystals are piezoelectric, so their mechanical characteristics can affect electronic circuits (see mechanical filter). In particular, quartz crystals can exhibit mechanical res… Web4001 - 6000 MHz Cavity Band Pass Filters 6001 MHz - 10 GHz Cavity Band Pass Filters 10 GHz and Above Cavity Band Pass Filters Ceramic Band Pass Filters 100 - 1000 MHz Ceramic Band Pass Filters 1001 - 2000 MHz Ceramic Band Pass Filters 2001 - 4000 MHz Ceramic Band Pass Filters 4001 - 7500 MHz Ceramic Band Pass Filters
