Ceramic Cavity Filter

The high volume low cost.

Ceramic cavity filter.

Frequency range 400 mhz to 6 ghz. Miniaturization can reach new levels by employing dli high k ceramic materials. Apitech ceramic filters offer insertion loss that is less than an equivalent lumped element filter with a package size that is smaller than an equivalent cavity filter. Specializing in band pass notch and diplexing applications skyworks can cover a frequency range from 250 mhz to 7000 mhz with surface mount or connectorized devices.

Cavity filters offer the user very low insertion loss steep skirt selectivity and narrower bandwidths than discrete component filters. From lc filters 5mhz to 10ghz cavity filters 100mhz to 26ghz including ceramic loaded designs plus ceramic cavity filters 100mhz to 12ghz for surface mount and connectorised applications using monoblock and discrete ceramic cavity designs. Skyworks is a world class supplier of high performance ceramic band pass filters. But it is very lossy due to large e r.

It uses a transmission line which the dielectric is cemaric very high e r about 40 90 also high q. Ceramic filters ceramic filters are manufactured in two basic styles for both commercial and military applications. Our line includes ceramic filters helical filters lc filters discrete lumped element filters cavity filters and we offer dielectric resonators and dielectric antennas. Utilizing state of the art assembly automation skyworks provides cost effective solutions meeting high performance specifications.

The result the filter will very small since the effectlive length reduces from the free space length by sqrt e r. Lowest insertion loss il highest attenuation rejection isolation highest q factor smallest size for specified performance highest power handling average and peak and sharpest transition slope. Cavity filter uses air as a dielectric for. Structure of cavity filter ceramic filter.

As the inventor of the ceramic monoblock 1982 cts has a unique intellectual property position which enables us to deliver the best ceramic rf filters. Aaren technology can supply rf microwave filters for every application. Different techniques are employed to realize small size and high performance.
