摘要： A duplexer using a dielectric block and having stepped impedance resonators is disclosed. The duplexer comprising open ended resonators arranged in a front side of the dielectric block, shorted resonators arranged in a rear side of the dielectric block, first grooves for controlling receiving coupling at the receiving filter, second grooves for controlling transmitting coupling at the transmitting filter, and a plurality of recesses formed at the bottom of the dielectric block, extending from a first aperture of the open ended resonators to a second aperture of the shorted resonators. The duplexer according to this invention is miniaturized by excluding external elements and has excellent attenuation characteristics, and is being manufactured by simple processes.

摘要： A duplexer having dual coupled line characteristics is disclosed. With a small number of resonators and without using an external device such as a chip inductor or a chip capacitor, the signals of the receiving frequency can be improvingly damped. The diameters of the transmitting terminal dielectric filter resonators and the receiving terminal dielectric filter resonators are not same, but their diameters at an open terminal and at a short circuit terminal are made different from each other so as to differentiate a coupling amount at the short circuit terminal from that at the open terminal. Further, the transmitting terminal filter resonators and the receiving terminal dielectric filter resonator are provided in a form of grooves, and sizes of the grooves near the open terminal are made different from those of the grooves near the short circuit terminal so as to differentiate a coupling amount of the resonators at the short circuit terminal from those at the open terminal. The duplexer of the present invention is used in the transmission/receiving separate type filter of the mobile communication.

摘要： A magnetostatic wave filter that includes a ferromagnetic substance stacked on one side of a dielectric substrate, one side of which is grounded, and the filter includes an input section having an input transfer line and an input energy transformer for causing the energy transformation between an electromagnetic wave and a magnetostatic wave, and an output section having an output energy transformer for causing the energy transformation between the electromagnetic wave and the magnetostatic wave and an output transfer line. The width of exciting lines in the input energy transformer and the output energy transformer varies in a longitudinal direction, the filter includes a shield film formed of a grounded conductive film having holes through which a magnetic thin film can pass between the input section and said output section, to prevent coupling of an electromagnetic wave.
