Abstract
An integrated structure of power amplifier and acoustic wave device comprises: a compound semiconductor epitaxial substrate including an epitaxial structure formed on a compound semiconductor substrate, a power amplifier upper structure formed on a top-side of a left part of the compound semiconductor epitaxial substrate, and a film bulk acoustic resonator formed on the top-side of a right part of the compound semiconductor epitaxial substrate; wherein the left part of the compound semiconductor epitaxial substrate and the power amplifier upper structure form a power amplifier; the right part of the compound semiconductor epitaxial substrate and the film bulk acoustic resonator form an acoustic wave device; the integrated structure of power amplifier and acoustic wave device on the same compound semiconductor epitaxial substrate is capable of reducing the component size, optimizing the impedance matching, and reducing the signal loss between power amplifier and acoustic wave device.
