Ceramic Resonator Circuit Design

For example murata offers the ceralock series ceramic resonators.

Ceramic resonator circuit design. Oscillating frequency may drift depending upon the controlling ic and or external capacitors c 1 and c 2 used in the circuit design. Because its operation is similar to a crystal it can be used in the same oscillator configurations. 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. Product lineup technical reference application support documents pdf.

The most common oscillator circuit for a ceramic resonator is a colpitts circuit. A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached. The resonators should not be operated beyond the operating temperature range specified in the catalog. Unlike rc or lc circuits ceramic resonators utilize mechanical resonance.

A ceramic resonator s equivalent electric circuit is identical to a quartz crystal. The resonant frequency is determined by the substrate s thickness. The ceramic resonator is half the size of comparable devices. Low price non adjustable ceramic resonators are mass produced resulting in low cost high stability and reliability.

Mini circuits offers a broad range of ceramic resonator filters specifically designed for gnss applications including both off the shelf models and custom designs. Token standard resonator is adjusted with our standard measuring circuit. Although the basic configurations of the circuit is the same as that of a crystal controlled oscillator the difference in mechanical q results from a. Typical oscillation circuit the most common oscillator circuit for a ceramic resonator is a colpitts circuit.

5 6 spurious characteristics for a typical ceramic resonator csb455e fig. There are various resonators that are used for an immense number of applications in the field of electronics. This means the resonator is not basically effected by external circuits or by. Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment.

The design of the circuit varies with the application and the ic to be used etc. Ceramic resonators ceralock ceramic resonators ceralock are made of high stability piezoelectric ceramics that function as a mechanical resonator. 5 3 electrical equivalent circuit for a ceramic resonator fig. 5 4 equivalent circuit for a ceramic resonator in the frequency range of fr f fa fig.

The design of the circuit varies with the application and the ic to be used etc. Changes drifts in oscillating frequency. 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. 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.
