Abstract
A method and system mitigates receiver desensitization caused by a reverse inter-modulation distortion (IMD) signal generated by a power amplifier associated with one of at least two concurrently operating transmitters. A power amplifier controller (PAC) determines whether at least one power amplifier operating in a first operating state generates a reverse IMD signal that can substantially interfere with at least one receive channel due to a concurrent operation of at least two concurrently operating transmitters. In response to determining that at least one power amplifier generates the reverse IMD signal when in the first operating state, the PAC initiates a second operating state of the power amplifier to increase the linearity of the at least one power amplifier in order to reduce the reverse IMD signal. The PAC initiates the second operating state by adjusting parameters of the power amplifier.
