Patent ID: 8565806

Claim:
A method of controlling output power of a radio transmitter, the method comprising: while operating the radio transmitter at an initial power level setting, making a first output power measurement of a radiofrequency signal generated from a source baseband signal; adjusting the first output power measurement by an incremental value; comparing the adjusted output power measurement with a first measured power level of the source baseband signal to obtain a theoretical target gain measurement; adjusting a power level setting of the radio transmitter; while operating the radio transmitter at the adjusted power level setting, making a second output power measurement of the radio frequency signal generated from the source baseband signal; comparing the second output power measurement with a second measured power level of the source baseband signal to obtain an actual gain measurement; ascertaining a difference value representing a difference between the theoretical target gain measurement and the actual gain measurement; and using the ascertained difference value to determine a further power adjustment of the radio transmitter that will reduce the difference between the theoretical target gain measurement and a subsequent actual gain measurement.
