1. A method for controlling a circuit within a transmitter, the method comprising:

  • calibrating an output power of a power amplifier integrated within a chip using an on-chip resistor that models an impedance of an antenna that is externally coupled to said power amplifier when in a transmit mode, wherein;

    said calibrating comprises coupling said power amplifier to said on-chip resistor when said power amplifier is decoupled from said antenna and measuring a power level at one or more stages in a transmit chain in the transmitter; and

    said one or more stages are located prior to an output of said power amplifier.
