Abstract:
1. A method of calibrating a transmitter circuit having a first characteristic controllable by a first control signal and a second characteristic controllable by a second control signal, the method comprising: defining a set of multiple signal values for the first control signal; defining a set of multiple power values representing power in a signal transmitted by the transmitter; setting the first control signal to a level corresponding to a signal value from the set of multiple first control signal values; selecting a power value from the defined set of multiple power values; adjusting the second control signal to cause the transmitter to transmit a signal with a power corresponding to the selected power value; repeating the selecting and adjusting for each power value in the set of multiple power values; and minimizing a power supply current drawn by an amplifier over a dynamic range of the transmitter through at least a one of defining of a set of multiple signal values, defining of a set of multiple power values, setting of the first control signal, selecting and adjusting.
