description Methods and apparatus, including computer program products, are provided for tunable filters. In one aspect there is provided an apparatus. The apparatus may include a bandpass filter comprising a resistive-capacitive configuration of N-path filters tunable to a first center frequency based on at least a first clock frequency; a notch filter comprising a capacitive-resistive configuration of N-path filters tunable to a second center frequency based on at least a second clock frequency; and a combiner coupled to the bandpass filter and the notch filter to combine a bandpass output signal provided by the bandpass filter and a notch output signal provided by the notch filter, wherein the combiner outputs a combined output. Related apparatus, systems, methods, and articles are also described.
