Abstract

PURPOSE:To ensure a better connection between the input and the output of a coaxial filter, by using the electrostatic capacity of a coaxial cable. CONSTITUTION:An interstage connection is secured by forming the metallic patterns 53-55 on the dielectric substrate 60 of a resonance circuit consisting of the resonators 30-32 plus the frequency adjusting screw 90. A connection is given between the input and output by using the electrostatic capacity between the central conductor 112 and the external conductor 110 of the coaxial cables 100 and 400. In the same way, a coaxial cable can be used also for an interstage connection. Accordingly an optional capacity can be realized to vary freely the degree of connection by using a coaxial cable for a connection between the input and output as well as between the stages.
