Abstract

PURPOSE:To obtain good pass characteristics as well as to ensure an easy electric adjustment through a simple constitution by combining the cavity resonator with use of both the magnetic and electric field combinations together in order to obtain the attenuation pole. CONSTITUTION:The 1st-4th cavity resonator 2-5 are installed in box 1; the longitudinal connection is given via coupling windows 8-10 between resonators 2 and 3, 3 and 4 and 4 and 5 respectively; and 1st and 4th resonators 2 and 5 are put to be adjacent to each other. Thus, the microwave entered through waveguide 10 of the input side is connected to resonator 2 and 2 via window 6 and then delivered through the waveguide of the output side through resonators 3-5 and via window 7. The above connections are all given via the magnetic field combination. Here, metal bar 21 which is insulated from the metal wall via insulator 23 is pierced through between resonator 2 and 5 in order to secure the electric field combination between these two resonators. In such way, the opposite phase is secured between the signals of the magnetic field and electric field cominations, thus producing the attenuation poles with the frequency with which the same amplitude is obtained for both cominations. The frequency is adjusted via screw 22.
