摘要： Aspects of this disclosure relate to an acoustic wave filter that includes acoustic wave resonators arranged to filter a radio frequency signal. The acoustic wave resonators include a first acoustic wave resonator. The acoustic wave filter includes a circuit element in parallel with the first acoustic wave resonator in a stage of the acoustic wave filter. The circuit element and the first acoustic wave resonator have different resonant frequencies. The circuit element can reduce an impact of bulk mode of the first acoustic wave resonator on insertion loss of the acoustic wave filter. The first acoustic wave resonator can be a surface acoustic wave resonator in certain embodiments. The circuit element can be a second acoustic wave resonator or a capacitor, for example.

摘要： Switchable and/or tunable filters, methods of manufacture and design structures are disclosed herein. The method of forming the filters includes forming at least one piezoelectric filter structure comprising a plurality of electrodes formed on a piezoelectric substrate. The method further includes forming a micro-electro-mechanical structure (MEMS) comprising a MEMS beam formed above the piezoelectric substrate and at a location in which, upon actuation, the MEMS beam shorts the piezoelectric filter structure by contacting at least one of the plurality of electrodes.

摘要： A mechanical filter device comprises a casing having housed therein a U-shaped tuning fork. A damper extends from the casing between adjoining vibratable tines of the tuning fork to effectively dampen abnormal vibrations of the tines caused by external shocks or impacts being applied to the casing. The damper is formed integrally with the casing as a one-piece structure from synthetic resin.

摘要： An electromechanical reed filter has a pair of reed elements secured at one end to each other and supported on a base member. A electromechanical transducer is cemented to the side surface of each of the reed elements intermediate of the opposite ends of the reed. The reed filter is housed in a protective casing and is provided with a shock-absorbing member in the vicinity of the free ends of the reed elements. When an abnormal shock is applied to the filter the reed elements are caused to bend transversely and would strike the inner walls of the casing with the shock-absorbing member being interposed therebetween. The impact energy is effectively absorbed so that the cemented portion of the transducer is protected from deformation or cracks. The shock-absorbing member may be applied to the free ends of the reed elements so that spurious vibrations at frequencies higher than the fundamental frequency can be suppressed.
摘要翻译：机电式簧片过滤器具有一对簧片元件，一对固定在一起并支撑在基座上。机电换能器胶合到筘的相对端的中间的每个簧片元件的侧表面。簧片过滤器容纳在保护壳体中，并且在簧片元件的自由端附近设置有减震构件。当对过滤器施加异常的冲击时，使得簧片元件横向弯曲，并且将冲击吸收构件插入其间，撞击壳体的内壁。冲击能被有效地吸收，从而保护换能器的胶结部分免受变形或裂纹的影响。减震构件可以施加到簧片元件的自由端，使得可以抑制高于基频的频率处的寄生振动。

摘要： An electromechanical band-pass filter is provided with transducers to convert electrical energy to mechanical motion, or convert mechanical motion to electrical energy. Each transducer includes a magnetic member and a coil member movable relative to each other. The magnetic member is supported on a leaf spring for movement in a plane parallel to the surface of a ferromagnetic member. Each coil member comprises a flat coil mounted on a ferromagnetic member, each coil having straight conductor segments extending at a right angle to the relative motion.
