Surface acoustic wave (SAW) filters are a type of filters that are based on surface acoustic waves created by crystals such as quartz. These waves propagate over the surface of a crystal and can be manipulated to filter out certain frequencies. The B39389L9654M100 is a SAW filter specifically designed for cellular communications applications. This article will discuss the application field and working principle of the B39389L9654M100.

The B39389L9654M100 is a SAW filter that has been specifically designed for cellular communication applications. It is a multi-mode, low-frequency pass filter that is designed to be integrated into the radio frequency (RF) front-end of GSM and WCDMA handsets. It can also be used in CDMA, PCS, and LTE applications. It has a wide passband frequency range of 534 MHz to 2.1 GHz, and a low insertion loss of 0.8 dB. The filter has excellent rejection properties, with a >22.5 dBc out-of-band rejection at 2.150 GHz.

The working principle of the B39389L9654M100 is based on surface acoustic waves. Surface acoustic waves are created when two piezoelectric materials are layered together and an acoustic wave is generated at an interference angle. This wave is then propagated across the surface of the crystal. By manipulating the wave properties, it is possible to filter out certain frequencies. The B39389L9654M100 uses a combination of thin-film layers and nickel electrodes to create and control the acoustic waves. This allows it to filter out unwanted frequencies, while also providing high selectivity and low insertion loss.

The B39389L9654M100 is an ideal filter for use in cellular communication applications. It has a wide passband frequency range, low insertion loss, and excellent rejection properties. Its surface acoustic wave design provides reliable performance and accurate filtering. The filter is easy to integrate into a variety of RF front-end designs, making it a popular choice for cellular communication applications.
