Surface acoustic wave (SAW) filters have a wide range of applications in the modern telecommunications industry. One of the most prominent uses of SAW filters is in mobile phones. Through the use of SAW filters, mobile phone users can enjoy crystal clear audio, access broadband data services, and even receive signal with minimal interference.

The B39451B3737H110 SAW filter is part of the B39451H110 series of low-cost surface-mount devices. This filter is specifically designed to meet the requirements of narrowband radio frequency (RF) applications. This filter operates in the frequency range of 400MHz-420MHz, making it suitable for wireless communications such as Wi-Fi, Wi-Max and Bluetooth.

The B39451B3737H110 has an extremely low insertion loss over its frequency band, providing maximum signal throughput. Even within the narrow frequency range of 400MHz-420MHz, this filter provides a rejection band of over 40dB, making it highly effective at eliminating unwanted signals.

As with all SAW filters, the B39451B3737H110 works by converting electrical signals into acoustic waves. These acoustic waves travel through the SAW substrate, where they encounter an array of electrodes which are tuned to resonate at the desired frequencies. The SAW filter then uses these electrodes to convert the acoustic waves back into electrical signals, allowing only the signals of desired frequencies to pass through.

The B39451B3737H110 is also designed with an additional element, the shunt damping plate, to provide superior selectivity. The shunt damping plate works by introducing a viscous damping element into the SAW filter substrate. This damping element not only helps to reduce the overall insertion loss of the device, but also helps to improve the selectivity by introducing additional damping at the frequencies of interest.

In addition to its use in mobile phones, the B39451B3737H110 SAW filter is also suitable for other wireless communications applications. This filter can be used for Wi-Fi, Wi-Max and Bluetooth applications, as well as system-on-chip (SoC) designs for devices such as digital cameras and sensors. It can also be used for receiver switches, mobile base station applications, and other high-bandwidth RF applications.

The B39451B3737H110 SAW filter is a low-cost, high-performance device that is ideal for use in a wide range of wireless communication applications. It offers a low insertion loss and a high degree of selectivity, making it well suited for applications such as mobile phones, digital cameras, and wireless base station transmitters. Its shunt damping plate also provides superior selectivity to ensure maximum signal throughput and reliable performance.
