Working Principle

The 8Y50070001 Crystal consists of three parts: a membrane thin enough to be considered as a film, a substrate, and electrodes on both sides of the membrane. When an electronic signal is transmitted to the electrodes, the pressure applied to the membrane makes it vibrate in a certain frequency. The electrodes absorb and convert the motion energy of the membrane vibration into an electric energy that induces an energy reflecting from the pressure signal from the vibrating membrane.

This signal is then rectified, amplified and filtered and re-transmitted from the electrode as an output signal. The frequency at which the membrane vibrates is known as the “operating frequency” of the Crystal. Different operating frequencies of crystal can be obtained by selecting different membrane materials, adjusting the thickness or stiffness of the membrane, and adjusting the positions of the electrodes.

In summary, 8Y50070001 Crystal is operated by transmitting an electric signal to electrodes that absorb and convert the motion energy of a vibrating membrane into an electric signal. Its operating frequency can be adjusted by adjusting the membrane parameters.

Conclusion

The 8Y50070001 Crystal is a rigidity and light weight Surface Acoustic Wave filter applicable in a variety of medical devices, smart home appliances, and handheld devices. Its working principle is to transmit an electric signal to the electrodes, absorb and convert the motion energy of the vibrating membrane into an output signal. The operating frequency can be adjusted by adjusting the membrane parameters.
