Abstract
An electrical impedance transformer comprises a first film bulk acoustic resonator (FBAR), having a first electrical impedance and a first resonance frequency. The electrical impedance transformer also comprises: a second FBAR, having a second electrical impedance and a second resonance frequency, and being disposed over the first FBAR. The electrical impedance transformer also includes a decoupling layer disposed between the first and the second FBARs. The first electrical impedance differs from the second electrical impedance and the first and second resonance frequencies are substantially the same.
