Ceramic Resonator Circuit Design

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.

Ceramic resonator circuit design.

Low price non adjustable ceramic resonators are mass produced resulting in low cost high stability and reliability. 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. The resonant frequency is determined by the substrate s thickness. Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment.

There are various resonators that are used for an immense number of applications in the field of electronics. Product lineup technical reference application support documents pdf. Oscillating frequency may drift depending upon the controlling ic and or external capacitors c 1 and c 2 used in the circuit design. The most common oscillator circuit for a ceramic resonator is a colpitts circuit.

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. A ceramic resonator s equivalent electric circuit is identical to a quartz crystal. Typical oscillation circuit the most common oscillator circuit for a ceramic resonator is a colpitts circuit. Token standard resonator is adjusted with our standard measuring 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 design of the circuit varies with the application and the ic to be used etc. 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. 5 6 spurious characteristics for a typical ceramic resonator csb455e fig.

Changes drifts in oscillating frequency. 5 7 basic configuration for an lc oscillation. The resonators should not be operated beyond the operating temperature range specified in the catalog. 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. For example murata offers the ceralock series ceramic resonators. Because its operation is similar to a crystal it can be used in the same oscillator configurations. This means the resonator is not basically effected by external circuits or by.

5 3 electrical equivalent circuit for a ceramic resonator fig. Ceramic resonators ceralock ceramic resonators ceralock are made of high stability piezoelectric ceramics that function as a mechanical resonator. Unlike rc or lc circuits ceramic resonators utilize mechanical resonance. The ceramic resonator is half the size of comparable devices.
