Radio frequency filtering circuitry
Abstract:
RF filtering circuitry includes a common node, a first input/output node, a second/input output node, a first filter coupled between the common node, the first input/output node, and the second input/output node, and a second filter coupled between the common node, the first input/output node, and the second input/output node. The first filter is configured to provide a first bandpass filter response between the common node and the first input/output node, where the first bandpass filter response is configured to pass RF signals within a first subset of the first frequency band while attenuating other signals. Further, the first filter is configured to provide a bandstop filter response between the common node and the second input/output node, where the bandstop filter response is configured to attenuate RF signals within the first subset of the first frequency band while passing other signals.
