This paper describes the calculation method of the rated power transmission coefficient of surface acoustic wave device working in the linear state, and derives the necessary relations for the practical application. Based on the known characteristics of acoustic transducers and acoustic cables, it is possible to calculate the loss of the device and the radio electronic device during the cross-linking operation and evaluate the non-uniformity of the amplitude-frequency characteristic of the device.
