Description:

Crystal filter, a filter composed of crystal resonators. Compared with LC resonance circuit of the filter, crystal filter in the frequency selectivity, frequency stability, intermediate gradient and insertion loss is much more superior, has been widely used in communications, navigation, measurement and other electronic devices.

Single chip crystal filter adopts integrated technology, which has the advantages of small volume, high stability and low cost. The band pass is usually made, and quartz crystal is used as the substrate. The working frequency range is 5 ~ 200MHz, and the relative bandwidth is about 0.01% ~ 0.3%. Because it works in the same way as the mechanical filter, also known as the single-chip machine gun filter, the filter can also be composed of multiple pieces of single chip to reduce the process requirements.
