SAW Filter The surface acoustic filter is composed of a metal film evaporated on a material substrate with a piezoelectric effect, and then photolithographed to form a pair of interdigitated electrodes at both ends. When a signal voltage is applied to the transmitting transducer, an electric field is formed between the input interdigital electrodes, causing the piezoelectric material to mechanically vibrate and propagate to the left and right sides in the form of ultrasonic waves. The energy toward the edge is absorbed by the sound-absorbing material. absorb. At the receiving end, the mechanical vibration is converted into electrical signals by the receiving transducer and output by the interdigitated electrodes. Surface acoustic wave filters are mainly used for signal processing and frequency selection in wireless communications and electronic equipment. It can filter signals within a specific frequency range, suppress unwanted frequency components, and retain the frequency signals of interest. HCI provides surface acoustic filters with different package sizes, different frequencies, and different bandwidth requirements. They are widely used in communications, radio, audio processing and other fields. They are indispensable in modern wireless communication systems and high-quality sound processing equipment. part.
