ABSTRACT:
Dielectric parts 12 which become resonators are fitted in holes formed in a dielectric substrate 11 and magnetic parts 13 for setting resonance frequencies of the dielectric parts 12 are also fitted in holes formed in the dielectric substrate 11. With such construction in which the dielectric parts are fitted in the holes of the dielectric substrate, the physical preciseness of a high frequency filter is improved. Further, by fitting not only the dielectric parts 12 but also the magnetic parts 13 in the holes of the dielectric substrate 11, it is possible to form the high frequency filter operating in a frequency band of several tens GHz as a micro wave integrated circuit to thereby improve the uniformality and mass-producibility of the high frequency filter.
