Abstract:
A voltage-controlled resonator, comprising:a first dielectric;a resonant circuit formed inside and/or on the first dielectric, the resonant circuit including a first plurality of circuit elements;a second plurality of circuit elements on a surface of the first dielectric, the second plurality including at least a choke circuit and a capacitor film;a variable-capacitance element mounted on an upper surface of said first dielectric;a second dielectric provided over the upper surface of the first dielectric, and defining a through-hole at a position corresponding to a position of said variable-capacitance element; anda shield film on or inside the second dielectric so as to shield elements that determine the resonant frequency of the resonant circuit, the circuit elements shielded by the shield film including a portion of the resonant circuit and the second plurality of circuit elements.
