Patent ID: 8134818

Claim:
A surge suppressor for protecting electronic equipment by suppressing surges of low frequency electromagnetic signals in a radio frequency (RF) transmission line while allowing RF signals of a desired frequency range to pass through said transmission line, said transmission line being provided by a cable, said surge suppressor comprising: a center pin having a length, a longitudinal axis, and at least one end providing a first plate of an isolation capacitor; at least one interface pin conductively coupled to a segment of said cable and capacitively coupled to said center pin, said at least one interface pin providing a second plate of said isolation capacitor; at least one stub having a length, said at least one stub providing a short circuit for diverting said surges of low frequency signals to a ground; and a housing incorporating said center pin, said at least one stub, and said at least one interface pin; wherein said desired frequency range depends upon said stub length and said center pin length.
