<p>According to the HIPER-LAN 2 system standard for wireless data communication, the output power Pout in each case needed at the transmitting end of the devices involved in the data communication is determined by control which, however, is associated with corresponding effects on the ratio between output power and power dissipation at the transmitting end. According to the invention, in particular, amplifier stages 2, 4, 5 with power dissipation in the data signal path of the transmitting device of such devices are in each case only supplied with the amount of power Psupply required for maintaining the linearity in the data signal processing depending on the required output power Pout. This reduces the power dissipation in such devices and improves the efficiency.</p> |
