System for combining and amplifying two broadband signals

摘要

The circuit combines and amplifies two wide-band signals from different transmission networks (NET1, 2). The signals ore transmitted in difference frequency channels. A preamplifier amplifies one received signal to provide a defined ratio of signal levels between the two signals. A frequency combiner (FW), with two inputs and one output, combines the two wide-band signals, and a wide-band amplifier (BV) amplifies the combined signals.
