Abstract
A surge suppressor for protecting electronic equipment by suppressing damaging surges of low frequency signals in a radio frequency (RF) transmission line, while allowing RF signals of a desired frequency range to pass through the transmission line. The surge suppressor can comprise a housing, a center pin connected to a stub, and at least one interface pin conductively coupled to the cable and capacitively coupled to the center pin. The surge suppressor can have a signal pass through bandwidth approximately 10 times exceeding the bandwidth of traditional quarter wavelength stub (QWS) devices, a higher return loss, and higher surge attenuation level. The surge suppressor can be symmetrically insertable into a cable providing an RF communication line.
