Ceramic Resonator Circuit Design

The most common oscillator circuit for a ceramic resonator is a colpitts circuit.

Ceramic resonator circuit design.

Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment. Typical oscillation circuit the most common oscillator circuit for a ceramic resonator is a colpitts circuit. Low price non adjustable ceramic resonators are mass produced resulting in low cost high stability and reliability. Product lineup technical reference application support documents pdf.

Mini circuits offers a broad range of ceramic resonator filters specifically designed for gnss applications including both off the shelf models and custom designs. The ceramic resonator is half the size of comparable devices. The design of the circuit varies with the application and the ic to be used etc. Because its operation is similar to a crystal it can be used in the same oscillator configurations.

5 6 spurious characteristics for a typical ceramic resonator csb455e fig. This means the resonator is not basically effected by external circuits or by. 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. A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached.

Unlike rc or lc circuits ceramic resonators utilize mechanical resonance. 5 4 equivalent circuit for a ceramic resonator in the frequency range of fr f fa fig. 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. There are various resonators that are used for an immense number of applications in the field of electronics.

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. 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.

For example murata offers the ceralock series ceramic resonators. The resonators should not be operated beyond the operating temperature range specified in the catalog. Ceramic resonators ceralock ceramic resonators ceralock are made of high stability piezoelectric ceramics that function as a mechanical resonator. The resonant frequency is determined by the substrate s thickness.

5 5 impedance and phase characteristics for ceramic resonators fig. Token standard resonator is adjusted with our standard measuring circuit. 5 7 basic configuration for an lc oscillation. Oscillating frequency may drift depending upon the controlling ic and or external capacitors c 1 and c 2 used in the circuit design.
