SAW Filters are devices built from Surface Acoustic Wave (SAW) technology and are based on the interaction of the acoustic wave with the interdigitated electrodes on the surface of a piezoelectric substrate. B38202W1054W310 is a high-performing SAW filter that has several applications and a noteworthy working principle.

Application Field

The B38202W1054W310 SAW filter is suitable for use in a variety of systems that require optimum performance in narrowband and wideband scenarios. In modern systems, where high levels of radio wave are generated, resonance and oscillation generated by such signals are a threat to their performance. A SAW filter is an ideal way to protect these systems, by attenuating and suppressing the undesired signals, while still allowing the desired signals to pass through. This type of filter can be used in wireless communication systems, such as cell phones, Wi-Fi routers, base stations, satellite radio, and wideband applications.

In addition to its radio-frequency interference (RFI) rejection, the B38202W1054W310 SAW filter also offers superior group delay performance. This makes it a great choice for applications where signals need to be accurately separated or timed with each other, such as automated test equipment, signal analyzers and medical imaging. It can also be used for a variety of other purposes, including providing input protection for switches and relays, replacing bulky filters found in receivers, and stabilizing digital-to-analog and analog-to-digital circuits.

Working Principle

At the heart of the B38202W1054W310 SAW filter is the acoustic wave that is generated on the piezoelectric substrate, which is composed of quartz or similar material. The signal that is passed through the filter is vibrated by mechanical resonance, which creates an acoustic wave that interacts with interdigitated electrodes on the substrate\'s surface. This filtering process creates a signal which has a specific frequency response.

The B38202W1054W310 SAW filter incorporates various technologies, such as resistance-capacitance and impedance-loss, to shape the filter\'s frequency response. With this combination of technologies, it is able to achieve a very narrowband response, along with high input impedance and low insertion loss. It is also designed for high isolation to reject any unwanted signals and improve signal purity.

The B38202W1054W310 SAW filter is also designed for maximum stability and reliability. It is designed to maintain its performance under harsh temperature and vibration conditions, and it is also resistant to moisture and aging. This makes it an ideal choice for applications requiring long-term performance.

Conclusion

The B38202W1054W310 SAW filter is a high-performance device that has applications in a variety of systems with demanding requirements. Its working principle is based on the interaction of a surface acoustic wave with the interdigitated electrodes on a piezoelectric substrate, which allows it to achieve a narrowband response with high input impedance and low insertion loss. Additionally, it is designed for maximum reliability and stability, making it a great choice for applications where long-term performance is needed.
