A method for transmission of data signals using a switched mode power amplifier, 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 data signals from a transmitting device (BS) to at least one receiving device (RAH1) using a switched mode power amplifier (PA), wherein the data 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), the data signals and radio frequency carrier signals are converted into optical signals and combined, the combined data signals are transmitted over at least one optical connection (OF1) from the transmitting device (BS) to the at least one receiving device (RAH1), and said combined data signals are amplified in a second part of the switched mode power amplifier (PA) in a switched output stage (SOS), a switched mode power amplifier, a transmitting device, a receiving device, and a communication network therefor.
