Ceramic Resonator Filter

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.

Ceramic resonator filter. 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. Ceramic resonators introduction to ceramic resonators ceramic resonators utilize the mechanical resonance of piezoelectric ceramics. Coaxial resonators are manufactured as quarter wave or half wave and as multiresonator blocks. Less demanding applications such as impedance matching or tuning will benefit from.

Ceramic resonators ceralock ceramic resonators ceralock are made of high stability piezoelectric ceramics that function as a mechanical resonator. Ceramic resonators look similar to ceramic filters.

Ceramic resonator technology can also be used in electronic circuit design to provide a bandpass filter. Our dielectric resonator materials are custom blended and sized to suit the individual filter or oscillator design. This diagram shows the impedans and frequency behavior in a 455khz ceramic filter. Ceramic filters are frequently used in the if stages of superheterodyne receivers.

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. Tem mode coaxial ceramic resonators and blocks. Catalog of trans tech s rf components. Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment.

Custom rf microwave filters and ceramic resonators for any application. 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. 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. The filters have three connections rather than the two used for the basic ceramic resonator.

As you can see the main resonans is at 455khz but there are several other resonans frequency. Product lineup technical reference application support documents pdf. Leaded ceramic passband filters showing the three connection pins input output common.
