Abstract

PURPOSE:To achieve band blocking filter with a simple construction and good characteristics without dispersion, by fixing a fixed electrode to an external wall of dielectric substance of a component of a resonator and keeping the coupling capacity constant with the area between the inner conductor and the fixed electrode. CONSTITUTION:Each resonator is coupled with a signal transmission line 8 with a 1/4 intube wavelength interval via a coupling capacitor consisting of inner conducttor of components 21-25 of the resonators and fixed electrodes 41-45, contact electrodes 61-65, and through-holes 71-75 to form a band block filter. Since the electrodes 41-45 forming the coupling capacitor are fixed at the side wall of dielectric substance of the elements 21-25, the capacitance is not changed by external oscillation. The coupling capacitance is determined through the area between the inner conductor and the fixed electrodes 41-45, and the characteristics can be made constant by keeping this area constant.
