ABSTRACT:
An LC-type dielectric filter which includes strip lines on a dielectric plate forming distributed constant type resonators. The strip lines and other elements of the filter, such as coupling capacitances are plated onto the dielectric plate as printed circuits to realize a small, high-Q dielectric filter which is suitable for mass-production.
