Abstract:
1. An apparatus for attenuating CW signals within at least one specified frequency band while allowing substantially baseband pulse signals to propagate therethrough with relatively little attenuation comprising: a main transmission line along which said CW and substantially baseband signals propagate; and at least one stub transmission line each of a predetermined length, characteristic impedance and terminated with a preselected impedance coupled in parallel relationship to said main transmission line with predetermined spacing therebetween, said predetermined length and said preselected impedance dependent upon said specified frequency band and said predetermined length being such that a baseband pulse initially coupled thereto from said main transmission line and reflected from said preselected impedance is returned to said main transmission line after an elapsed time, from said initial coupling, that exceeds the duration of said substantially baseband pulse.
