Abstract

PURPOSE:To achieve sufficient attenuation to a desired frequency component, by constituting a dual tuning circuit which uses two resonators and inserts a grounding line, and coupling the output conductor from the grounding line to a resonator distributed constant line at the output side. CONSTITUTION:A distributed constant line 21 the both ends of which are grounded is inserted betwen the 1st and 2nd distributed constant lines 15, 17, and a filter is made small in size through critical coupling state without great distance between the lines 15, 17. One end of a thin output conductor 22 is connected to a suitable position of the line 21 and this is coupled with the 2nd distributed constant line through crossing and connected to an output line 20', allowing to provide a trap frequency around the center frequency. This trap frequency can be adjusted by changing the location of the output lead 22.
