摘要： A communications device comprises a receiver for receiving an input signal operably coupled to analogue to digital converter logic. The analogue to digital converter logic is operably coupled to control logic via a signal analyzer arranged to analyze a converted received input signal, output from the analogue to digital converter logic to determine at least one characteristic of the received signal. The control logic is arranged to vary a dynamic range of the analogue to digital converter logic depending on the at least one determined characteristic of the received input signal.

摘要： A wireless communication unit comprises a transmitter having a power amplifier and a feedback path operably coupled to the power amplifier. The feedback path comprises a coupler for feeding back a portion of a signal to be transmitted and a detector for detecting a power level of the fed back signal. A controller provides a ramp signal to the power amplifier that controls an amplitude characteristic of the signal to be transmitted. Averaging logic is operably coupled to the detector and arranged to average the detected power level over a first period. Comparison logic is operably coupled to the averaging logic and arranged to compare the average detected power level with a reference value. The controller is operably coupled to the comparison logic and arranged to scale a ramp signal applied to the power amplifier in response to the comparison.

摘要： Receiver circuitry for processing a received Very Low Intermediate Frequency signal wherein the receiver circuitry comprises a main processing path. The main processing path comprises mixing circuitry arranged to mix a received VLIF signal with a frequency down conversion signal to produce a main path signal. The receiver circuitry further comprises a direct current cancellation path comprising mixing circuitry arranged to mix a DC element of the received VLIF signal with the frequency down conversion signal to produce a DC cancellation signal. The receiver circuitry still further comprises signal summing circuitry arranged to add the DC cancellation signal in anti-phase with the main path signal.
