SAW Filter refers to surface acoustic wave filter (Surface Acoustic Wave Filter). It is an electronic filter which can realize precise frequency control. The B39241B3865H510 SAW Filter is a high-frequency SAW filter that complies with RoHS and 4-REN standards. Its frequency range is from 915MHz to 925MHz, and it is composed of two single-frequency acoustic wave filters.

The application field of the B39241B3865H510 SAW Filter mainly covers product terminals that require RoHS and 4-REN standards in the telecommunications industry. For example, these products can be used in products such as mobile phones, computers, and other products which require RoHS and 4-REN standards.

The working principle of the B39241B3865H510 SAW Filter is similar to other SAW filter applications. It uses surface acoustic waves on piezoelectric film and electronic processing to filter out the frequency you want to pass through. The crystal substrate on which the SAW filter is mounted is called “host substrate”. The piezoelectric film is a thin film-like material on the host substrate, and when an external electric field is applied to the film, acoustic waves will be generated near the surface of the substrate. At the same time, the reflection of the acoustic wave will be used to compensate for the attenuation of the acoustic wave and increase the filter band width.

The main operational characteristics of the B39241B3865H510 SAW Filter are a typical insertion loss of 2.5 to 3dB, a maximum operating temperature of 105℃, and a temperature coefficient of 0.002%. It also has a termination impedance of 50ohm and a fail-safe characteristic of -42dBm.

In order to further explain the working principle of B39241B3865H510 SAW Filter, let\'s take mobile phones as an example. The B39241B3865H510 SAW Filter is actually used as a frequency splitter in the mobile phone. It is responsible for splitting the signal of the base station into different frequency bands and processing them separately. This is done by the B39241B3865H510 SAW Filter to improve the signal-to-noise ratio of the receiver and extend the range of the transmission. In addition, the B39241B3865H510 SAW Filter block band is also used in mobile phones to prevent signals from being transmitted at certain frequencies and prevent interference.

In summary, the B39241B3865H510 SAW Filter is a cost-effective SAW filter which can meet the needs of the telecommunications industry. It is mainly used in the product terminal that requires the RoHS and 4-REN standard. Its working principle is to use surface acoustic waves on piezoelectric film and electronic processing for precise frequency control. The main operational characteristics of the B39241B3865H510 SAW Filter is a typical insertion loss of 2.5 to 3dB, a maximum operating temperature of 105℃, and a temperature coefficient of 0.002%.
