摘要： The present disclosure relates to a transmitter for transmitting a transmit signal comprising a first signal portion and a second signal portion. The transmitter comprises a power amplifier configured to amplify the transmit signal. The power amplifier is prone to undesired gain variations during the first and the second signal portion. The transmitter further comprises a transmit feedback receiver coupled to an output of the power amplifier and configured to feed back the transmit signal to generate a fed back first signal portion and a fed back second signal portion. Processing circuitry is configured to determine a first gain relation between the fed back first signal portion and the first signal portion and to determine at least one second gain relation between the fed back second signal portion and the second signal portion. Power adjustment circuitry is configured to adjust a transmit power of the transmit signal according to a variation between the first gain relation and the second gain relation.

摘要： Embodiments relate to a concept for determining a transit of a movable object through a detection area within a detection plane. At least one exciter antenna provides an exciting electromagnetic field. The exciting electromagnetic field or at least one spatial component thereof has a field strength above a field strength threshold in the detection area. The exciting electromagnetic field is capable of exciting the movable object to emit an electromagnetic response signal comprising information on a position of the movable object. At least one sensor antenna comprising a magnetic core receives the electromagnetic response signal. The at least one magnetic core is positioned in a region of the exciting electromagnetic field where the field strength of the exciting electromagnetic field or the at least one spatial component thereof is below the field strength threshold.

摘要： A synthesizer circuit to generate a local oscillator carrier signal for a baseband signal includes a controlled oscillator comprising a phase lock loop and an oscillator configured to generate an oscillating signal. A pulling compensation circuit is configured to generate a correction signal for a present output of the phase locked loop using information on an error of the oscillating signal, information on a present sample of a baseband signal and a preceding correction signal for a preceding output of the phase locked loop.

摘要： A radio frequency signal synthesizer circuit includes a digital to analog converter configured to generate an analog output signal for each clock cycle of a clock signal to provide the radio frequency signal and a controlled oscillator to generate the clock signal. The controlled oscillator is configured to vary a cycle time of the clock signal for a radio frequency signal in a first frequency range in a first operation mode or to maintain a constant cycle time for a radio frequency signal in a second frequency range in a second operation mode, the second frequency range being different than the first frequency range.
