IEC 61019-2:2005 gives practical guidance to the use of surface acoustic wave (SAW) resonators which are used in telecommunications, radio equipments and consumer products. It is to be used in conjunction with IEC 61019-1. The features of SAW resonators are small size, light weight, adjustment-free and high stability,operating frequencies extend to the VHF and UHF ranges. The main changes with respect to the previous editon are listed below: - at the end of 5.1, the edge reflector has been added. Its reference literature has been inserted in the bibliography; - in Table 1, the propagation properties of LiNbO3 (64° Y) have been added; - in Table 3, the clause and subclause numbers have been corrected in order to be consistent with IEC 61019-1 (2004) which has replaced IEC 61019-1-1 (1990) and IEC 61019-1-2 (1993).
