A method for transmission of signals, a switched mode power amplifier, a transmitting device, a receiving device, and a communication network therefor

摘要

The invention concerns a method for transmission of signals from a transmitting device (BS) to at least one receiving device (RAH1) using a switched mode power amplifier (PA) for signal amplification, wherein the signals are modulated in a first part of the switched mode power amplifier (PA) in a delta sigma modulator (DSM) that is located in the transmitting device (BS), said signals are transmitted over at least one optical fiber (OF1) from the transmitting device (BS) to the at least one receiving device (RAH1), and said signals are amplified in a second part of the switched mode power amplifier (PA) in a switched output stage (SOS) that is located in said at least one receiving device (RAH1), a switched mode power amplifier, a transmitting device, a receiving device, and a communication network therefor.
