Using first principles and the constitutive equations for a piezoelectric, we solve the 2-D acoustic wave inside a single, infinite, piezoelectric membrane to study the dispersion of thin film bulk acoustic resonator (FBAR) lateral modes, with and wi

Using first principles and the constitutive equations of a piezoelectric crystal, we solve the 2-D problem inside a three-layer film bulk acoustic resonator (FBAR) in order to study the dispersion and parasitic lateral modes’ characteristic of the

A new multi-FBAR structure concept purposely invented and patented for higher power handling capability is presented. In order to reduce self-heating under large RF signal, the thermal resistance and energy flow concepts are approached through a deta

Coupled resonator filters designed using a single-layer coupler require coupling materials with an acoustic impedance less than 5.0 MRayl. Carbon-doped oxide, with an acoustic impedance of 4.8 MRayl and an acoustic attenuation of 200 to 600 dB/cm at

We discuss the operation of novel coupled-resonator filters with single-layer acoustic couplers. Our analysis employs the physical Mason model for acoustic resonators. Their simpler fabrication process is counterbalanced by the high acoustic attenuat

Accurate modeling of a bulk acoustic wave resonator frequency response is limited by the inability of the current 1-D models to simulate certain parasitic modes excited in realistic 3-D structures. A simple technique is proposed to simulate such para

A systematic approach to matching an arbitrary number of bulk acoustic wave or surface acoustic wave filters is proposed. The filters can be modeled as capacitor networks at frequencies above and below their passbands. The generic matching network co

Two filter applications, GPS and Wi-Fi, using bulk wave coupled resonator filters (BWCRF) are discussed. The device consists of two FBAR resonators stacked one on top of the other and separated by a thin de-coupling layer. We refer to this device as

Coupled resonator filters extend the use of classical FBAR/BAW filters by enabling them to convert single-ended signals into differential signals while using a much smaller wafer real estate. In lieu of the traditional multi-layer de-coupling structu
