Abstract
A device including automatic gain control for balancing losses in a coaxial transmission path of a network is disclosed. The device includes a fixed gain bidirectional amplifier, an equalizer circuit for equalizing the loss of a fixed amount of cable a circuit for providing a variable amount of loss for simulating a variable amount of coaxial cable, and a closed loop system for monitoring the signal strength of an outbound pilot signal. The closed loop system provides for adjustment of the variable simulator circuit so that the sum of the losses provided by the coaxial transmission path, the equalizer circuit and the variable simulator circuit are equal in amplitude to the gain of the fixed gain amplifier across the entire inbound and outbound bandwidth of the network.
