Abstract
A monolithic LC filter which provides increased magnetic field coupling as compared with a conventional monolithic LC filter, without an increase in component size of the filter. The monolithic LC filter includes first and second resonator inductors coupled together by magnetic field coupling. The inductors include parallel-extending straight coupling sections formed by conductive lines which extend in parallel generally along a diagonal of a supporting dielectric layer. This configuration enables the lengths of the coupling sections to be increased as compared with the lengths of the corresponding coupling sections of a conventional monolithic LC filter.
