<p><P>PROBLEM TO BE SOLVED: To realize a complex RF device which includes a plurality of functions and features of small size and low height, in a high-definition state, without damaging the crystallinity of piezoelectric body. <P>SOLUTION: The complex RF device is constituted of two RF circuits stacked in the vertical direction. The complex RF device comprises a substrate, a second RF circuit provided on the substrate, and a first RF circuit which is provided on the second circuit and dispenses with a substrate. The first RF circuit is formed on another substrate, before being transferred onto the second RF circuit. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
