Abstract: Wireless circuitry is provided that includes an amplifier configured to receive a radio-frequency signal, a measurement circuit coupled to a power supply terminal of the amplifier and configured to output a measured value, and control circuitry configured to adjust one or more components associated with the amplifier based on the measured value output from the measurement circuit. The measurement circuit can include a transformer or a current mirror circuit. The control circuitry can selectively adjust an input matching circuit, an output matching circuit, and/or one or more bias voltages for the amplifier based on the measured value. The control circuitry can switch one or more amplifiers in and out of use depending on the measured value.

Abstract: A two-point modulator arrangement is specified, said arrangement being developed with respect to conventional two-point modulators to the effect that the high-pass coupling-in point of the modulator that comprises a phase locked loop is formed by an expanded loop filter. In accordance with the present principle, the expanded loop filter comprises a coupling-in element, at which the modulation signal is combined with the output signal of a phase comparator. A voltage-controlled oscillator having only one tuning input can thus advantageously be used.

Abstract: This transmission method serves to transmit information between a base station (BS) and a multiplicity of subscriber stations (MS) in transmission channels of a broadband signal. The transmission channels can be distinguished by different codes (Cs, C1, . . . , Cq) which modulate the broadband signal and which themselves are each modulated by the information to be transmitted in the respective transmission channel and are superimposed in the broadband signal. In this context, there is provision for at least one of the transmission channels (for example Cs) to be emphasized, as a prioritized transmission channel, in comparison with the other transmission channels (C1, . . . , Cq), in that its phase angle is shifted by a fixed amount in comparison with the phase angle of the other transmission channels.
