Surface acoustic wave (SAW) filters are used as frequency selective elements in radio systems. They are composed of interdigital electrodes, with one electrode per interdigital finger, printed on the surface of a piezoelectric substrate, for example, quartz or lithium niobate. An incoming signal is converted into a SAW by the input interdigital transducer and propagates along the surface of the substrate. It is then reflected by the output transducer and its phase is “scanned” by the phase shifter within the filter. The filter is thus tuned to the frequency of interest and passes it to the output while suppressing all other frequencies.

B39841B8768P810S1 is an example of a SAW filter, an advanced filtering technology used in a wide range of applications. B39841B8768P810S1 has a low insertion loss and a wide passband resulting in increased productivity and cost savings. It is designed to provide high-quality signal filtering in devices where a frequency is the key factor. It is suitable for controlling the frequency of digital signals, especially in systems where signal bandwidths are narrow. Furthermore, the device is able to provide low-noise, wide-passband signal filtering for many types of applications, including cellular phone systems, mobile radio applications, WLAN and other high-frequency communication systems, as well as GPS, radar, satellite broadcast, and other communication systems.

The working principle of B39841B8768P810S1 is based on the piezoelectric effect. When a voltage is applied to the interdigital electrodes, two mechanisms are produced – a vertical one and a lateral one. The vertical component of the mechanism is responsible for generation and transmission of the SAW along the surface of the substrate, while the lateral component is designed to reflect the SAW. By tuning the phase shifter, the reflected SAW can be made to come out of phase with the forward SAW, thus canceling out any frequency components that it may contain. This makes it possible to suppress undesired frequency components and transmit only those that fall within the desired frequency band.

B39841B8768P810S1 is a versatile and reliable SAW filter that can be used in a wide range of applications. It is designed to provide high-quality signal filtering in mobile and wireless communication systems, WLAN, GPS navigation systems, satellite broadcasting systems, radar detection systems, and other types of communication systems. In addition, the device can also be used for adjustable frequency control in digital signal processing systems, as well as for controlling the frequency of analog signals from RF sources.
