1. A method for correcting transmit power of a radio device having a plurality of predetermined calibration values and a reference voltage signal, the radio device transmitting and receiving on a plurality of frequencies, each frequency having a frequency index, the method comprising the steps of:

  • receiving a first signal having a first gain, a first frequency of the plurality of frequencies, and the first frequency having a first frequency index;

    determining a receive power value of the first signal;

    generating an automatic gain control setpoint in response to the receive power value and the reference voltage signal;

    selecting a first predetermined calibration value in response to the automatic gain control setpoint and the first frequency index;

    adjusting the first gain in response to the first calibration value;

    transmitting a second signal having a second gain and a second frequency of the plurality of frequencies, the second frequency having a second frequency index;

    determining a transmit power value of the second signal;

    generating a second calibration value in response to the automatic gain control setpoint, the second frequency index, and the transmit power value; and

    adjusting the second gain in response to the second calibration value.
