ANTENNA AMPLIFIER, RECEIVING SYSTEM, OPERATING METHOD, AND USE OF A RECEIVING SYSTEM

摘要

An antenna amplifier, receiving system, operating method, and use of a receiving system, is provided. The antenna amplifier includes a first signal input and a second signal input for connecting antennas, a first amplifier circuit connected to the first signal input and having a first digital control signal input for receiving a first digital control signal for setting an amplification of the first amplifier circuit and a first signal output, a second amplifier circuit connected to the second signal input and having a second digital control signal input for receiving a second digital control signal for setting an amplification of the second amplifier circuit and a second signal output, a summator connected to the first signal output and the second signal output for outputting a sum signal to a sum signal output, and a digital gain controller with a digital command signal input for receiving a digital command signal and a digital control signal output for outputting the first digital control signal and the second digital control signal.
