  • DC cutting circuit
    Patent number: 4800343
    Abstract: A DC cutting circuit for passing a signal having a selected wavelength from input side circuitry to output side circuitry while cutting from said signal any DC component therein, which includes a resonator electrode having an electrical length of 1/4 wavelength and formed at a forward open end of a strip line connected to an input side circuitry, and another resonator electrode also having an electrical length of 1/4 wavelength and formed at a forward open end of a strip line connected to an output side circuitry, with said resonator electrodes being disposed in a parallel spaced relation to each other so as to couple the input side circuitry with the output side circuitry by the two resonator electrodes.
