发明名称 Dielectric filter device
摘要 <p>A dielectric device is provided which comprises a dielectric resonator element having a plurality of resonators arranged in parallel with each other, a multilayer circuit element having conductive patterns constituting a coupling circuit, the conductive patterns being laminated vertically while alternating with dielectric layers, the circuit element being rectangular and having a pair of opposite vertical side surfaces, the coupling circuit having first connecting ends disposed at the first vertical side surface and second connecting ends disposed at the second vertical side surface, a plurality of vertical conduction grooves disposed at the first vertical side surface, the conduction groove having open upper ends and electrically connected to the first connecting ends of the coupling circuit, a plurality of metallic terminal members fitted in respective through holes of the resonators and thereby electrically connected to inner conductors of the resonators while being fitted in the conduction grooves and thereby electrically connected to the first connecting ends of the coupling circuit, and a printed board mounting thereon the resonator element and the circuit element and having external connecting terminals electrically connected to the second connecting ends of the coupling circuit. &lt;IMAGE&gt;</p>
