SAW (surface acoustic wave) or bulk acoustic wave (BAW) filters are type of frequency selective filter, which enables frequency-specific signal generation and transmission. Broadly speaking, a SAW filter uses one or more transducers such as quartz crystals, to propagate an acoustic wave within a surface acoustic wave (SAW) structure. This wave then passes through the passband filter, with the desired frequencies being passed and other frequencies being blocked.

The B39142B1666U510W3 SAW filter is a sub-miniature filter designed for use in mobile and hand-held communication devices. This filter is highly applicable in many class-leading projects including mobile, base-stations and datacom, with the range of noise attenuation up to 52dB. This filter also offers a high rejection level and low insertion loss, and a narrow selectable passband.

The B39142B1666U510W3 SAW filter’s application field is: cellular/basestation commercial communication systems; microwave point-to-point systems; portable battery-powered communication devices; radio communication systems.The use of this filter has a variety of benefits, such as it helps to increase system performance by reducing interference; it provides a clean signal by suppressing unwanted signals arising from multi-channel interference. Additionally, it offers excellent return loss, phase and amplitude tracking abilities with reduced group delay variance.

The working principle of the B39142B1666U510W3 SAW filter is as follows: the radio frequency signal is applied to the SAW filter via a port and excites the surface acoustic wave (SAW) structure on a piezoelectric substrate, such as quartz. The acoustic wave is then propagates along the SAW structure, with the filtering action occurring as the wave passes through the several structures. As the wave passes through, the filters can block specific frequency bands before the signal exits the device. The signal then exits the filter and is then ready for further processing or application.

In a typical implementation, the B39142B1666U510W3 SAW filter is used in conjunction with a suitably large substrate material, such as quartz or plastic. This substrate serves as the basis for the SAW structure, which consists of a printed spiral array of transducers, also known as resonators. The transducers are used to convert the incoming and outgoing RF (radio frequency) signal into an acoustic wave. The acoustic wave is then propagated along the SAW structure as it passes through the several layers of SAW filters, performing its filtering action. Once the signal has been filtered, it exits the device ready for further processing.

The B39142B1666U510W3 SAW filter is a high-performance frequency filtering solution suitable for a variety of applications. It has the ability to provide a clean signal with a high rejection level and a narrow selectable pass-band. Additionally, it boasts excellent return loss, phase and amplitude tracking abilities, reduce group delay variance, and a range of noise attenuation up to 52dB, making it well suited for many applications, from mobile and portables communication devices, to cellular/basestation commercial communication systems, to microwave point-to-point systems and radio communication systems.
