FBAR 

Film Bulk Acoustic Resonator:

is a device consisting of a piezoelectric material sandwiched between two electrodes and acoustically isolated from the surrounding medium. FBAR devices using piezoelectric films with thicknesses ranging from several micrometres down to tenths of micrometres resonate in the frequency range of roughly 100 MHz to 10 GHz

The duplexer in most cellphones is based on FBAR filters
