Abstract
A signal processing device implemented in a semiconductor body includes a frequency conversion device and a converter connected to the frequency conversion device. The conversion device is coupled by a terminal to a terminal on the surface of the semiconductor body. One terminal of the converter is connected to a terminal node of the signal processing device. A signal generator, which is connected by its signal output to a local oscillator input of the frequency conversion device, has a control input for setting its operating point. Furthermore, a control circuit is provided. In this case, an output of the control circuit is connected to the control input of the signal generator. Depending on internal signals which identify an operating state of the signal processing device, the control circuit generates a regulating signal at the output. The operating point of the signal generator is thereby set in such a way that a current consumption of the signal processing device is reduced, so that the signal quality is ensured in a sufficient manner.
