摘要： Disclosed is a method for providing ability of tuning resonance frequency in different applications. The method according to the invention at least comprises the step of adding ferroelectric disks in the resonators. Here, the ferroelectric disks have the relative dielectric constants varying according to change of ambient environment. In the invention, since the resonance frequency can vary according to the ambient environment, the tuning range of filters and duplexers/multiplexers having the resonators with ferroelectric disks is large. In addition, the resonance frequency can be changed in high frequency environment according to the invention. So, the invention can be used to improve the size and cost of the filters and duplexers/multiplexers in different applications, especially in low noise environment.
