摘要:
A structure and method to reduce second order intermodulation (IM2) of a receiver in a transceiver is provided. Specifically, the output of a detector in a transmit power control loop is utilized to calculate IM2 and the value is subtracted from a receive path to mitigate IM2 in a wireless communication devices. Alternatively, the detector can be placed in one or more receive paths to include receiver front-end passband variation.
