The amplifier has been designed for professional cable and MATV systems with return channel. This house/building amplifier is equipped with output stage using Gal-As semiconductor components, working in push-pull mode. The next innovation is driving stage, employing IC made of Si-Ge semiconductor. Such a solution significantly reduces non-linear distortions, especially of second order.
It enables signal level equalization in forward and return path.
It enables signal level equalization in forward and return path.
