  • Abstract
    Waveguide bandpass transmission filters, each stage of which is composed of two similar irises spaced a distance s apart, are considered. The distance between stages for effectively quarter-wave coupling is shown to be s±1/4λg/g. The loaded Q of one stage is computed, and the frequency consciousness of the iris susceptance is shown to have no effect on the spacing condition, but to have a substantial effect upon the loaded Q, especially for low values of Q.
