Abstract
Various techniques involving polar modulation are disclosed. For instance, an apparatus may include a storage medium and a calibration module. The storage medium stores multiple adjustment settings. Each of these adjustment settings corresponds to an operating condition. The calibration module selects one of the stored adjustment settings that corresponds to a current operating condition. With the selected adjustment setting, the calibration module reduces a polar modulation timing misalignment. The current operating condition may include one or more operational parameter values. Examples of such parameter values include output power level, signal frequency, and/or temperature.
