A communication device, method, and computer program product provide communication quality mitigation in response to an intermodulation product resulting from concurrent transmission by first and second transmitters of a communication device. A controller is communicatively coupled to the first and second transmitters and executes an intermodulation mitigation utility that enables the communication device to monitor transmission characteristics of first and second transmitters of the communication device. The controller determines whether concurrent transmissions by the first and second transmitters create an intermodulation product having a power level at one or more frequencies that exceeds an intermodulation threshold for at least one of: (i) spurious emissions to a thirty-party receiver; and (ii) desensing a receiver of the communication device. Controller enables communication device to perform reduced transmit power mode that reduces the power level of the intermodulation product to not exceed the intermodulation threshold and performs communication quality mitigation.
