Ceramic resonator circuit design.

Because its operation is similar to a crystal it can be used in the same oscillator configurations. 5 3 electrical equivalent circuit for a ceramic resonator fig. The resonators should not be operated beyond the operating temperature range specified in the catalog. The design of the circuit varies with the application and the ic to be used etc.

A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached. Ceramic resonators ceralock ceramic resonators ceralock are made of high stability piezoelectric ceramics that function as a mechanical resonator. Typical oscillation circuit the most common oscillator circuit for a ceramic resonator is a colpitts 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.

5 6 spurious characteristics for a typical ceramic resonator csb455e fig. The resonant frequency is determined by the substrate s thickness. 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. There are various resonators that are used for an immense number of applications in the field of electronics.

Changes drifts in oscillating frequency. 5 4 equivalent circuit for a ceramic resonator in the frequency range of fr f fa fig. Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment. The ceramic resonator is half the size of comparable devices.

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. Unlike rc or lc circuits ceramic resonators utilize mechanical resonance. The most common oscillator circuit for a ceramic resonator is a colpitts circuit. 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.

This means the resonator is not basically effected by external circuits or by. Token standard resonator is adjusted with our standard measuring circuit. A ceramic resonator s equivalent electric circuit is identical to a quartz crystal. For example murata offers the ceralock series ceramic resonators.

5 5 impedance and phase characteristics for ceramic resonators fig. 5 7 basic configuration for an lc oscillation. Low price non adjustable ceramic resonators are mass produced resulting in low cost high stability and reliability. Although the basic configuration of the circuit is the same as that of a crystal controlled oscillator the difference in mechanical q results from a.
