SAW Filters

RF1172 is a surface acoustic wave (SAW) filter designed for communication systems. It is most commonly used in radio and television broadcasting, satellite communications, and wireless communications, as well as automated factories in various industries. These high-performance filters can achieve high accuracy in frequency filter responses, which can help improve the performance of communication systems by eliminating noise and interference from the frequency range of the system.

Application Field of RF1172

RF1172 is mainly used in the wireless communication industry, such as FM radio, GSM, Bluetooth and short-range wireless transmission applications. Because of its excellent performance, RF1172 is also widely used in other related industries. It can effectively help improve the accuracy of automatic process control in industries such as robotics, automatic inspection systems, industrial control systems, automotive, weapons guidance and missile control.

Working Principle of RF1172

RF1172 is based on the principle of surface acoustic wave (SAW). It is based on the physical phenomenon that the acoustic wave propagating along the piezoelectric material surface travels at a relatively slow speed. When an electric field is applied to the piezoelectric material, the acoustic wave velocity changes, so the frequency of the signal is filtered and attenuated. The oscillation of the electric signal passes through the SAW filter to a certain degree of attenuation. The filtered signal will be modified and output.

The unique feature of RF1172 is that it uses two different frequencies of surface acoustic waves (SAW) to produce resonance in the filter. This resonance can work in different frequency bands and help to improve the signal-to-noise ratio. This filter also has an adjustable passband frequency filter, which can be manipulated according to a variety of applications. In addition, the high selectivity, high isolation and low insertion loss of RF1172 make it an ideal solution for communication systems.

Conclusion

RF1172 is a type of surface acoustic wave (SAW) filter that is widely used in communication systems. It has a wide range of applications, ranging from FM radio to GSM communication and automated factories in various industries. Because of its excellent characteristics such as adjustable passband frequency filter, high selectivity, and high isolation, it is a suitable choice for various communication systems. The working principle is based on the principle of SAW, which can effectively eliminate noise and interference from the frequency range of the system.
