Surface Acoustic Wave (SAW) filters are essential components in many modern electronic devices used for radio frequency (RF) filtering. They are used to block or attenuate undesired frequencies while allowing the desired frequency range to pass through. The B39901B4179U510 is an example of a SAW filter. This article will describe its application field and working principle.

The B39901B4179U510 SAW filter is designed to filter radio frequency signals in the range of 800 MHz to 2.7 GHz. This range covers most commonly used frequencies, including those used for mobile phone (GSM, CDMA, 3G, 4G) and broadband applications. It is a low-cost, highly efficient filter with a high suppression level of up to 70 dB. The filter also has a very small size, making it easy to integrate into new and existing designs.

The B39901B4179U510 SAW filter is based on the principle of acoustic energy propagation through a piezoelectric substrate such as quartz or ceramic. These substrates are made with electrical conductors placed around them in a certain pattern to create an interference pattern. The RF energy is introduced to the conductors which are then converted into acoustic signals and interact with the substrate, creating an interference pattern that has the effect of attenuating the undesired frequencies while allowing the desired frequencies to pass. This pattern also has the effect of creating an impedance mismatch for the undesired frequencies, further reducing their impact on the overall signal.

The B39901B4179U510 SAW filter is ideally suited for use in mobile phone, WiFi, and radio applications. In mobile phone applications, it can be used to filter out interfering signals while allowing the desired frequencies to pass through. In Wi-Fi routers, it can be used to filter out undesired frequencies which can cause interference with the desired signals. In radio applications, it can be used to filter out undesired signals from the desired frequencies.

The B39901B4179U510 SAW filter is a very cost-effective solution for filtering out undesired frequencies while allowing the desired frequencies to pass. It has a high suppression level, a small size, and is easy to integrate into existing designs. The filter is based on the principle of acoustic energy propagation through a piezoelectric substrate which creates an interference pattern that has the effect of attenuating the undesired frequencies while allowing the desired frequencies to pass. The filter is ideally suited for use in mobile phone, Wi-Fi, and radio applications.
