摘要： A small in-band-flat-group-delay type dielectric filter having low-loss characteristics with a small amplitude deviation and uniform-group-delay frequency characteristics is obtained, which enables broad-band characteristics to be obtained easily. The in-band-flat-group-delay type dielectric filter includes a plurality of dielectric coaxial resonators, a coupling circuit comprising a combination of reactive elements, with which the dielectric coaxial resonators are coupled to one another, and input/output terminals connected to ends of the coupling circuit. The dielectric coaxial resonators coupled to the input/output terminals are allowed to have a different characteristic impedance from that of the inter-stage dielectric coaxial resonators.

摘要： A dielectric laminated filter has a first dielectric laminated block including a first strip line electrode and a second dielectric laminated block including a second strip line electrode and a coupling element, wherein the first and the second dielectric laminated blocks are laminated via a first shield electrode and wherein the first and the second strip lines are connected via a third strip line. This configuration allows the unwanted electromagnetic coupling between a resonator and the coupling element to be neglected, and uses the third strip line electrode to form the first and the second strip line electrodes so that they extend across different layers, thereby enabling the size of the resonator to be reduced. In addition, since the third strip line electrode serves to adjust the filter characteristics, a small high-performance dielectric laminated filter that can be designed easily can be provided.
