Ceramic Filter

A ceramic filter is distinguished from other filters by the discrete ceramic structures that form each resonator. Each element introduces a transmission zero in the pass band of the filter. Coupling between the resonators is achieved by using fringe-field etched capacitors on an alumina substrate. This topology allows for narrow band structures with low insertion loss. However, only bandpass and bandstop filters are available.

The entire ceramic filter resembles a microwave combline filter with 90 degrees resonators. The term 90 degrees refers to the electrical length of the device at the operating frequency. For example, in a resonator, with a dielectric constant of 1, at a frequency of 1000 MHz, the electrical length is about 1 foot. Thus, 90 degrees is 3 inches. However, if the dielectric is changed to 36 the length scales by the inverse square root, resulting in a length of 0.5 inches. The advantage of a ceramic substrate is the reduction of length.

Filtronetics, Inc. offers ceramic filters of custom center frequency and bandwidth. The typical range for the center frequency is from 200 MHz to 3 GHz. Moreover, pass bandwidth can be from 1% to 15% of the center frequency. Ceramic filters are used principally in commercial, low cost applications. However, military and hi-reliability units are available. Ceramic filters are available in surface mount (SMD), through hole, and custom packages.
