Abstract

PURPOSE:To realize a simple and small-size structure for the filter as well as to secure the designed characteristics faithfully into the products by constituting the filter via the coaxial TEM resonator in which the dielectric is provided between the inner and outer conductors. CONSTITUTION:Coaxial TEM resonator 1 featuring the prescribed wavelength is constituted by providing dielectric 4 such as the ceramic dielectric between inner conductor 2 and outer conductor3. The inside of conductor 2 is formed into cavity with center rod 5 inserted and fixed, and electrode film 11 is formed to the projected terminal over the open end face unified with conductor 2 and with formation of terminal electrode 13 there. Then more than one unit of such resonator 1 are distributed within main case 16 along with input-use coaxial connector 21 and output-use coaxial connector 22 respectively. Then center conductor 23 and 24 of connector 21 and 22 are combined each other via dielectric rod 25, and electrode 13 is connected to connector 21 and 23 with some distance secured between. Thus, the filter using the coaxial resonator can be obtained.
