Ceramic Resonator Filter Circuit

Typical oscillator configuration with a ceramic resonator well that was a small glimt about ceramic filter and ceramic resonators.

Ceramic resonator filter circuit.

Mini circuits offers a broad range of ceramic resonator filters specifically designed for gnss applications including both off the shelf models and custom designs. This diagram shows the impedans and frequency behavior in a 455khz ceramic filter. In those list of resonators the two mainly used materials are quartz crystal and ceramic making ceramic resonator quartz crystal is used in crystal oscillator and ceramic is used in ceramic resonator both of them have the same aim of generating an oscillation frequency by vibrating. 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.

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. A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached. 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. Mini circuits offers a broad range of ceramic resonator filters specifically designed for gnss applications including both off the shelf models and custom designs.

Low insertion loss combined with excellent power handling. As you can see the main resonans is at 455khz but there are several other resonans frequency.
