Crystal bandpass filters use piezoelectric effect of quartz crystals and convert their own mechanical motion into electric signals. The low thermal expansion of Quartz crystals allows crystal filters to produce stable frequencies over a wide temperature range. They have higher Q factor than LC filters. Because of the property of Quartz, crystal filters are built upto 150 - 200 MHz. At higher frequencies, the crystal tends to be very thin, brittle and unreliazable.
