1. An acoustic resonator device comprising:
a piezoelectric plate having a front surface and a back surface opposite the front surface;
a back-side conductor pattern formed on the back surface; and
a first front-side conductor pattern and a second front-side conductor pattern formed on respective portions of the front surface opposite the back-side conductor pattern, wherein a portion of the piezoelectric plate between the first front-side conductor pattern and the back-side conductor pattern forms a first resonator and a portion of the piezoelectric plate between the second front-side conductor pattern and the back-side conductor pattern forms a second resonator.
