摘要：
This disclosure provides implementations of filters and filter topologies, circuits, structures, devices, apparatus, systems, and related processes. In one aspect, a device includes one or more LC resonant circuit stages. In some implementations, each LC stage includes an inductor and a capacitor. Each LC stage also has a corresponding resonant frequency. The one or more LC stages are arranged to produce an unmodified passband over a range of frequencies having a corresponding bandwidth. One or more microelectromechanical systems (MEMS) resonators are arranged with the one or more LC stages. The one or more MEMS resonators are arranged with the one or more LC stages so as to modify characteristics of the unmodified passband such that the hybrid filter produces a modified passband having a modified bandwidth and one or more other modified band characteristics.
