Abstract :
This paper presents for the first time a 7.45 GHz (C- band) bulk acoustic wave (BAW) filter successfully packaged on Liquid Crystal Polymer (LCP) multilayer organic material. Utilizing the inherent advantages of LCP allows for a near-hermetic package with minimal loss in performance. This work utilizes state-of-the-art BAW technologies and 3D packaging techniques to create significant benefits in terms of cost, size and performance. As BAW devices extend to higher microwave frequencies, this packaging approach exhibits potential for a viable low cost solution.
