Introduction

Surface Acoustic Wave (SAW) filters are used for signal processing in various applications, particularly in the telecommunications industry. These filters have the ability to modify signals by mixing them with additional signal components, or to provide signal isolation by rejecting unwanted signals. The B39871B3746H110 is a SAW filter developed by Infineon Technologies specifically designed for customer-oriented mobile radio applications. It provides a reliable alternative to the commonly used electric and intermediate frequency filters. This article will discuss the application field of the B39871B3746H110 and its working principle.

Application Field of B39871B3746H110

The B39871B3746H110 is specifically designed for customer-oriented mobile radio applications such as GSM, CDMA, and W-CDMA. In GSM applications, it is designed to filter signals received from a base station and transmit these signals to the mobile radio. Similarly, in CDMA applications, the B39871B3746H110 is used to filter signals received from both a base station and a subscriber unit. It has the ability to reject out-of-band interference and improve system performance by providing signal isolation. In W-CDMA applications, the B39871B3746H110 is used to filter signals received from a base station and a subscriber unit. It is also designed to reject out-of-band interference, which can improve system performance by providing better signal isolation and improved signal-to-noise ratio. The B39871B3746H110 can also be used in other signal processing applications, such as low-noise amplifiers, FM receivers, and television receivers.

Working Principle of B39871B3746H110

The working principle of the B39871B3746H110 can be broken down into three main components: reflection, transmission, and stop-band suppression. First, when a signal is sent into the filter, it is reflected off of the electrodes on its surface. The reflected signal is then reflected back out of the filter, creating a “reflection effect” that is used to modify the incident signal. This reflects both the amplitude and phase of the signal. Second, the filter is designed to transmit the desired signal components, and to suppress any unwanted components. This is done by the use of a transmission response that is designed to filter out any undesired frequencies. Finally, the filter is designed to suppress any frequencies outside the desired passband. This is done by using stop-bands which reject any frequencies that are outside the predetermined passband.

Conclusion

The B39871B3746H110 is a SAW filter that is specifically designed for customer-oriented mobile radio applications. It can be used in GSM, CDMA, and W-CDMA applications for signal processing. It is designed to provide efficient signal isolation of unwanted signals by using reflection, transmission, and stop-band suppression. This article discussed the application field of the B39871B3746H110 and its working principle, providing helpful insight into its uses in signal processing.
