Monolithic Crystals
Monolithic crystal filter (MCF) products are used in radio and related applications as bandpass filters. Closely related to the quartz crystal resonators used widely for frequency generation, MCF filters employ the piezoelectric and mechanical resonance properties of the quartz material to produce a filter with very high selectivity in a compact package.
