Ceramic Resonator Filter

Less demanding applications such as impedance matching or tuning will benefit from.

Ceramic resonator filter.

Originally ceramic filters were used as very low cost filters for broadcast radio receivers both medium wave sets with typical ifs of 455khz and fm broadcast sets with if stages at around 10 7mhz. Ceramic resonators ceralock ceramic resonators ceralock are made of high stability piezoelectric ceramics that function as a mechanical resonator. To learn more call our engineering hotline at 858 259 2600. Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment.

Long years of experience in the design and mass production of piezoelectric ceramic filters have enabled murata electronics to develop and produce economical and highly reliable ceramic resonators as a stabilization. Although they are slightly larger than l c filters ceramic resonator filters are still an acceptable size and cost for gnss application requirements. Tem mode coaxial ceramic resonators and blocks. Leaded ceramic passband filters showing the three connection pins input output common.

Product lineup technical reference application support documents pdf. Ceramic coaxial resonators with high q and very good temperature stability are perfectly suitable for oscillators and as elements of filters bandpass bandstop notch and duplexers typically. Trans tech designs space saving resonator filters with very low profile 2mm 1 85mm and 1 5mm for frequencies up to 7ghz and high power ceramic filters for frequencies up to 2ghz with power levels up to 100w. Coaxial resonators are manufactured as quarter wave or half wave and as multiresonator blocks.

The filters have three connections rather than the two used for the basic ceramic resonator. Typical oscillator configuration with a ceramic resonator well that was a small glimt about ceramic filter and ceramic resonators. This diagram shows the impedans and frequency behavior in a 455khz ceramic filter. Read more in this ceramic resonator filter presentation.

Catalog of trans tech s rf components. Ceramic resonators look similar to ceramic filters. Ceramic filters are frequently used in the if stages of superheterodyne receivers. Ceramic resonators introduction to ceramic resonators ceramic resonators utilize the mechanical resonance of piezoelectric ceramics.

Skyworks solutions through its wholly owned subsidiary trans tech offers proprietary ceramic materials to provide engineers the best solutions for size q factor temperature stability and cost. Ceramic resonator technology can also be used in electronic circuit design to provide a bandpass filter. Ceramic resonator filters by contrast can achieve high rejection and selectivity with much lower insertion loss typically 1 5 db or better than l c filters with comparable rejection performance.
