摘要

A method of transmitting data signals from a transmitting device (BS) to at least one dispositivoreceptor (RAH1) using an amplifier (PA) power in switched for signal amplification method, inthe which said data signals are transmitted by at least one optical connection (OF1) from the transmitting device (BS) to said at least one receiving device (RAH1), in which * the data signals are modulated on a delta sigma modulator (DSM) included in a first portion of amplifier (PA) of the switched mode power which is located in the transmitting device (BS), yielding resultadoseñales data modulated, * the modulated data signals are converted from electrical signals into optical data in a convertidorelectro-optical (EO1) in the first part of the amplifier (PA) of the switched mode power, characterized in that * the radio frequency carrier signals are converted, signal electrical to optical deradiofrecuencia carrier signals in a further electro-optical converter (EO2) in the first part of the amplifier (PA) of enmodalidad switched power * signals optical data are added to the carrier signals optical RF, yielding resultadoseñales optical combined data, * optical data signals combined are increased frequency from the signals of optical data dandocomo result signals electrical data with increased frequency, applying optical heterodyning in a converter (OE1) opto-electric, a second amplifier (PA) of the switched mode power is nestled in said at least one receiving device (RAH1), * and said signals of electrical data with increased frequency are amplified in the second amplifier (PA) power switched mode, a (SOS) switched output stage.
