Transmitter performance calibration systems and methods

A method of calibrating a communications device, the method comprising:

• generating a first transmit signal at a transmit frequency using performance parameters;
• tuning a receive chain to the transmit frequency;
• leaking a portion of the first transmit signal to the receive chain as transmit leakage;
• measuring the transmit leakage in the receive chain;
• and
• determining one or more reduced performance parameters based on the measured transmit leakage, wherein the one or more reduced performance parameters reduce performance of a transmitter;
• and
• generating the first transmit signal using one or more initial performance parameters and generating a second transmit signal at the transmit frequency using the one or more reduced performance parameters, wherein the second transmit signal has a reduced power consumption and an increased transmit leakage as compared with the first transmit signal.
