Abstract
A multi-band filter module and a method of fabricating the same are provided. The multi-band filter module includes a piezoelectric substrate, a first filter provided on the piezoelectric substrate, and a second filter provided adjacent to the first filter on the piezoelectric substrate, and operating in a frequency band that is lower than that of the first filter.
Claims6
A method of fabricating a multi-band filter module, the method comprising:
- (a) forming a Film Bulk Acoustic Resonator (FBAR) on a piezoelectric substrate;
- and
- (b) forming a Surface Acoustic Wave (SAW) device on the piezoelectric substrate;
- wherein the steps (a) and (b) are concurrently performed.
