1. A method of operating a dual frequency band transmit device, the method comprising:

  • determining if a transmit frequency in a first frequency band from the device combined with a transmit frequency in a second frequency band from the device causes receiver desensitization at the device;

    determining if transmit power in the first frequency band is above a threshold power; and

    reducing maximum transmit power in the second frequency band by an amount proportional to transmit power in the first frequency band and transmit signal bandwidth in the second frequency band if the transmit frequency in the first frequency band combined with the transmit frequency in the second frequency band causes receiver desensitization at the device and if the transmit power in the first frequency band is above the threshold power.
