Ceramic Resonator Filter Circuit

This diagram shows the impedans and frequency behavior in a 455khz ceramic filter.

Ceramic resonator filter circuit.

A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached. Mini circuits offers a broad range of ceramic resonator filters specifically designed for gnss applications including both off the shelf models and custom designs. Our ceramic resonator filters are designed with high q resonators that provide narrow passbands with low insertion loss ranging from 0 9 db to 3 0 db. When connected in an electronic oscillator circuit resonant mechanical vibrations in the device generate an oscillating signal of a specific frequency like the similar quartz crystal they are used in oscillators for purposes such as generating.

Bandpass and bandstop filters diplexerand multiplexer designs can be constructed using this technology. Mini circuits offers a broad range of ceramic resonator filters specifically designed for gnss applications including both off the shelf models and custom designs. Mini circuits coaxial ceramic resonator filters offer low insertion loss in very small form factors using ceramic material with high dielectric constant and superior q factor. Our ceramic resonator filters are designed with high q resonators that provide narrow passbands with low insertion loss ranging from 0 9 db to 3 0 db.

As you can see the main resonans is at 455khz but there are several other resonans frequency. Typical oscillator configuration with a ceramic resonator well that was a small glimt about ceramic filter and ceramic resonators.
