Abstract
In one embodiment of a transmitting output stage, a first controllable amplification device with a first amplification factor and a second amplification device with a second amplification factor are provided. The two amplification devices are connected on the input side to a signal input. The transmitting output stage comprises a first matching network, which is connected on the input side to an output of first amplification device. A second matching network is also provided, which is installed switchably between an output of the second amplifier stage and the input of the first matching network and which, in one operating mode of the transmitting output stage in which only the second amplifier stage is being used, is connected between the second amplifier stage and the first matching network. Other embodiments are also disclosed.
