SAW Filter Overview

Surface acoustic wave (SAW) filters are a type of digital filters that are used in a wide range of applications. SAW filters use surface acoustic wave (SAW) technology to filter out unwanted frequencies and amplify desired frequencies. They are designed to selectively pass desired frequencies and reject all other frequencies. SAW filters are commonly used in wireless networks and other RF applications, as well as in audio applications.

B39871B3941H110 Application Field and Working Principle

The B39871B3941H110 SAW filter is designed for use in mobile cellular radio systems. It is an optimized filter that offers excellent performance for GSM/EDGE applications. The filter has an insertion loss of less than or equal to 0.75 dB. It also offers a low spread of insertion loss and high radiation resistance. In addition, it has a wide input impedance bandwidth and a small size.The B39871B3941H110 uses the surface acoustic wave technology to filter out undesired frequencies and amplify desired frequencies. The filter consists of interdigital transducers (IDTs) and acoustic mirrors on a piezoelectric substrate. The IDTs generate an electromagnetic wave, which is then propagated on the surface of the substrate. This wave is then converted back into an electric signal by the IDTs. The acoustic mirrors help to reflect the energy of the radiation coming from the IDTs, thus ensuring a high level of isolation. The B39871B3941H110 filter also offers high frequency selectivity, low insertion loss, and high rejection of unwanted signals. It is also highly stable and robust, allowing it to function in a variety of different environments. In addition, the filter is designed to operate over a wide temperature range and is capable of withstanding harsh conditions. Overall, the B39871B3941H110 SAW filter is a versatile and reliable filter that offers superior performance for GSM/EDGE applications. It offers a wide input impedance bandwidth, high radiation resistance, and a low spread of insertion loss, making it an ideal choice for mobile applications.
