Abstract

This paper focuses on theoretical investigations on "Acoustic-Wave-Lumped-Element Resonator" (AWLR) modules that have gained much interest in the last few years regarding general progress in radio frequency (RF) filter techniques and design. It is shown how the bandwidth characteristics depend on the electro-mechanical coupling factor of the employed piezoelectric material. General approximation formulas for the achievable 3 dB-bandwidth and for the maximum achievable bandwidth of symmetric AWLR modules are given. The results of the mathematical derivation are verified by simulation.
