The authors have introduced the operation principle and methods for improving the characteristics of SAW and BAW devices in this chapter. Among the various MEMS resonators, SAW and BAW devices have been among the most successfully commercialised fields, particularly for wireless RF applications. The communication architecture was described, which is the common ground in device development. Also, the improvement of the characteristics has been described in terms of the requirements of such applications. With regard to techniques for improving performance, a very wide range of knowledge of engineering from materials to numerical dispersive analysis is required. The authorshave only given an outline of these fields. Details can be found in the books and papers cited in this chapter.
