ELECTRICAL RESONATOR DEVICE WITH A WIDE FREQUENCY VARIATION RANGE.

摘要

Electrical resonator device, capable of operating at variable frequency, ? comprising at least: - an acoustic wave resonator, - a first electrical circuit coupled in parallel to the resonator with an adjustable complex impedance whose imaginary part is equal to, where C1= 0, - a second electrical circuit coupled in parallel to the resonator and the first electrical circuit, with a complex impedance whose imaginary part is equal to, where C2 < 0, ? is the operating frequency of the device.
