Abstract
A wide-band high-frequency analog amplifier is provided in the signal path between an input cable connector and an integrated-circuit based cable equalizer. The amplifier is preferably a common base transistor amplifier. The amplifier serves multiple purposes, including providing additional gain to compensate for losses incurred in the equalizer, increasing return loss on the input line, and allowing different gain levels in the input stage and operating stages of the equalizer.
