Abstract: Methods and apparatus, including computer program products, are provided for a tunable filter. In some example embodiments, there may be provided an apparatus. In some example embodiments, there is provided an apparatus. The apparatus may include a tunable radio frequency filter including a tunable phase shifter coupled to a resonator, wherein the tunable phase shifter tunes a center frequency of the tunable radio frequency filter by at least varying a phase of a radio frequency signal provided to the resonator. Related apparatus, systems, methods, and articles are also described.
