Title: TRANSMITTER PERFORMANCE CALIBRATION SYSTEMS AND METHODS
Abstract:
An apparatus is disclosed that includes a transmit chain, a duplexer, a receive chain and a control circuit. The transmit chain is configured to generate a transmit signal at a transmit frequency. The duplexer is configured to pass the transmit signal to an antenna that generates a transmit leakage current into a received signal. The receive chain is configured to obtain the received signal and measure the leakage current from the transmit chain. The control circuit is configured to determine reduced performance parameters for the transmit chain based on the determined leakage signal, wherein the transmit leakage signal is inversely proportional to the reduced performance parameters.
