In order to prevent surface acoustic wave(SAW) devices from being burned by their own pyroelectric static electricity, a new electrostatic protection method is proposed in this paper. In this method, the conductive medium is adopted to realize good connection with the pins of SAW devices. An electrostatic conduction path is built to discharge the pyroelectric static, thus the problem that SAW devices are sensitive to the electrostatic discharge is solved. The experimental results show that the proposed method can effectively prevent electrostatic burns and has good practicability.
