摘要： A circuit arrangement includes two adjustable amplification devices where the signal output of the first amplification device is connected to the signal input of the second amplification device. The first amplification device has a digital input for controlling its gain and the second amplification device has an input for controlling its gain. The input for gain control in the second amplification device is connected to the input for controlling the gain of the first amplification device via a means such that a change in the gain of the second amplification device in one direction is effected by a change in gain, brought about by means of the control, in the first amplification device in the opposite direction such that the total gain remains essentially the same.

摘要： Conventional circuit configurations for range changeover between different bands (UHF, VHF) in television receivers utilize MOS tetrodes whose operating point adjustment is unproblematic. The MOS tetrodes of the inventive circuit configuration comprise a constant potential at their source electrode regardless of the band that is selected. Besides the savings in terms of components, the invention simplifies the dimensioning of the circuit configuration. The invention can be used in all high-frequency receivers having a plurality of frequency ranges between which a changeover is performed.

摘要： A transmitting and receiving unit includes a receiving branch and a transmitting branch that are in each case constructed for conducting complex signals, with a control device that drives a switch by which either a phase-locked loop is switched through to frequency converters provided at the transmitting and receiving end, for providing a common carrier frequency, or in each case an independently operating PLL is provided for the transmitting and receiving branch. Such a configuration enables the transmitter, for example, to operate with direct conversion whereas the receiver can operate, for example, on the low IF principle. The invention is suitable for OFDM multi-carrier systems.
