Abstract:
1. A transmission arrangement with power regulation, comprising: a transmission path comprising a digital signal processor for the digital processing of a useful signal to be transmitted, a digital/analog converter, which is connected downstream of the digital signal processor, and a modulator, which is coupled to an output of the digital/analog converter, for modulating a carrier signal with the useful signal to be transmitted, and which provides a radio frequency transmission signal at an output thereof; a power detector coupled to the output of the modulator; an analog/digital converter having an input coupled to the power detector and having an output coupled to the digital signal processor; and the modulator having a control input for setting the gain of the modulator, the control input coupled to the digital signal processor for permitting the amplitude of the radio frequency transmission signal to be influenced in a manner dependent on power measured by the power detector, wherein the gain of the modulator is influenced by individual mixer cells, and wherein each of the mixer cells is, independently of the other mixer cells, connectable into and disconnectable from parallel combination with any of the other mixer cells.
