Surface Acoustic Wave (SAW) filters are one of the most commonly used filters in the world today. They are applied to many areas, such as radio communications, television broadcasts, medical equipment and many more. The B39941B4380P810S5 is one of many SAW filters used in the industry. This article aims to describe the application field and its working principle.

The B39941B4380P810S5 is an ultra-miniature SAW filter for use in a wide variety of consumer electronics. It is suitable for numerous applications, including GSM/EDGE mobile phones, consumer electronics, computers and laptops. The filter has a rich feature set, including low insertion loss, high rejection performance, and a wide operating frequency range of 850-2050MHz.

The filter offers excellent performance with a low insertion loss of only 0.3dB over the 850-2050MHz band and a high rejection level of 40dB across the band. This makes it ideal for use in narrow band receivers and transmitters that need a wide rejection rate in order to reduce interference from other frequencies. It also offers a low group delay variation of only 0.3nS, ensuring that data is transmitted and received in an efficient manner.

The B39941B4380P810S5 works by utilizing the phenomenon of surface acoustic wave resonance to allow only certain frequencies to pass. This is accomplished by utilizing a layered structure containing two electrodes which are embedded in the filter material. When a signal is applied to the filter, it is guided across the two electrodes, and as the signal passes over the electrodes, it will cause the frequency-selective resonance of the surface acoustic wave. Only frequencies that match this resonance will be passed on, while others will be suppressed or rejected.

The B39941B4380P810S5 is a versatile filter that can be used in a wide range of applications. It is especially useful for applications requiring high rejection to reduce interference, such as radio and cellular communications, as well as medical equipment. In these areas, the B39941B4380P810S5 can help ensure signal integrity and reduce interference.

In conclusion, the B39941B4380P810S5 is an excellent SAW filter that provides high rejection and low insertion loss to ensure signal integrity. It is suitable for a wide range of applications, including radio and cellular communications, medical equipment and more. With its low group delay variation and high rejection performance, the B39941B4380P810S5 is an ideal choice for applications requiring RF filtering.
