Crystal Band Pass Filters(0.003-250 MHz)
Crystal bandpass filters use the piezoelectric effect of quartz crystals and convert mechanical motion into electric signals. The low thermal expansion of quartz crystals allows crystal filters to produce stable performance over a wide temperature range. This type of crystal pass band filters exhibit extremely high Q factor, giving them the ability to achieve extremely narrow bandwidth in the range of a few kHz. Such a high Q factor, in the range of 5000 and higher than 10000 results in relatively low loss considering their extremely narrow bandwidth. The crystal band pass filters are available in frequencies up to 250 MHz, in connectorized, surface mount, PC board mount, and drop-in type packages, with a length ranging from approximately 1 to 5 in.
The Crystal bandpass filter is just one of the many products that Anatech Electronice offers to RF design engineers looking for quality filters and RF microwave products. Contact us today for quality, service and top customer experience.
