COMBINATION SURGE AND DIPLEX FILTER FOR CATV DISTRIBUTION SYSTEMS

摘要

A combination surge and diplex filter is provided for a CATV distribution amplifier. In a first preferred implementation, an integrated surge and high pass filter section (40) is provided when the CATV amplifier is used only in the forward direction. Provision is made for a plug-in low pass filter section (45) which is matched to the high pass filter section (40). The plug-in low pass section (45) is used to form a diplex filter if the reverse direction capability of the CATV system is required from the distribution amplifier. In a second preferred implementation, the integrated surge and high pass filter section is segmented into a surge filter segment which is designed as a divisible part of the high pass filter section.
