Abstract
A frequency extraction filter is disclosed. The frequency extraction filter can include a resonator that is coupled to a first node, and a phase shifter that is connected to the resonator in series. The phase shifter is coupled to a second node such that the resonator and the phase shifter are positioned between the first and second nodes. Impedance between the first and second nodes has an order of four or more.
