A method of calibrating a polar amplification stage including a main signal path and a magnitude signal path, the method comprising: generating signals (108, 142) for the main signal path and the magnitude signal path for operating an amplifier (102) between a linear mode of operation and a saturated mode of operation; detecting (114) first and second peaks in a signal at the output of the amplifier (102) representing transitions between the linear and saturated modes of operation; and adjusting (124) the timing in one of the main signal path and the amplitude signal path in dependence on a relative difference between the size of the detected first and second peaks. |
