Patent ID: 7515884

Claim:
A method for performing self-calibration of a transmitter, the method comprising: transmitting a first wireless signal at a first power level; measuring signal power of the first wireless signal at an output of a power amplifier with an internal power detector; receiving data representative of signal power of the first wireless signal measured from a device receiving the first wireless signal; correlating, as a first correlated power detector measurement, the internal power detector measurement of the first wireless signal with the data representative of the signal power of the first wireless signal measured from the device receiving the first wireless signal; transmitting a second wireless signal at a second power level; measuring signal power of the second wireless signal at the output of the power amplifier with the internal power detector; receiving data representative of signal power of the second wireless signal measured from a device receiving the second wireless signal; correlating, as a second correlated power detector measurement, the internal power detector measurement of the second wireless signal with the data representative of the signal power of the second wireless signal measured from the device receiving the second wireless signal; and interpolating a desired power detector value for at least one operating point based on the first and second correlated power detector measurements, wherein the at least one operating point includes a frequency and a desired output power.
