Abstract
A device and method for reducing intermodulation within a radio receiver. The device includes an intermodulation filter. The intermodulation filter is configured to receive a signal, apply a first filter and a second filter to the signal to generate a first and a second filtered signal. The intermodulation filter is configured to isolate a first intermodulation component located on a first side of a frequency spectrum of the signal within the second filtered signal, determine an estimated second intermodulation component based on a potential frequency band location, determine a correction factor based on an amplitude and phase relationship between the first and second intermodulation components, apply the correction factor to the estimated second intermodulation component, determine if the second intermodulation component exceeds a predetermined power threshold, and apply the adjusted estimated second intermodulation component to the first filtered signal, suppressing the second intermodulation component.
