Introduction

Surface acoustic wave (SAW) filters are a type of electromagnetic filter. It is basically an electronic filter which uses acoustic waves. It has several advantages over traditional filters such as higher filter order (i.e. more selective) and better temperature stability (i.e. temperature-independent performance over a wide range of temperatures). SAW filters are used in a wide range of applications, including satellite communication, radar, fixed-wireless communication, GPS, and cellular base stations. The B39122B1605U810 is a SAW Filter used for waveform generation and filtering applications. It is a typical example of a modern SAW filter which provides broad-band performance and temperature stability.

Application Field and Working Principle of B39122B1605U810

The B39122B1605U810 is used for applications such as cellular communication systems, broadband wireless networks, L-band satellite communication systems, automotive in-vehicle systems, television spectrum, and GPS signal distribution. The device provides a SAW filter for telecom basestations and other applications operating in the frequency range of 800 MHz to 2.6 GHz. The B39122B1605U810 SAW filter consists of two identical parts: a resonator and an input transducer. The resonator is composed of a 2-dimensional piezoelectric substrate. It has electrodes that are printed on the surface of the substrate and form a series of strips connected in parallel. The electrodes and substrate are then sandwiched between two metal plates. When a high frequency signal is applied to the input transducer, it generates surface acoustic waves that travel across the substrate. The waves interact with the electrodes and form a resonance. The resonance is then mirrored by the metal plates and the signal is reflected back to the input transducer. The input transducer, on the other hand, is responsible for providing a high frequency input signal that can be filtered. It comprises of a piezoelectric substrate and two sets of electrodes. When an electric field is applied to the input transducer, it creates a mechanical strain which in turn causes the generation of surface acoustic waves. The signal is then converted back to an electric field and is filtered by the SAW filter.The application field and working principle of the B39122B1605U810 SAW Filter have been discussed above. The device is especially popular because of its broad-band performance, temperature stability and high insertion loss. It is also easy to use and reliable, making it suitable for use in a range of applications. Additionally, it has a low cost, making it a viable option for a variety of applications.

Conclusion

In conclusion, the B39122B1605U810 SAW Filter is a cost effective and reliable solution for filtering and waveform generation applications in the frequency range of 800 MHz to 2.6 GHz. It has several advantages over traditional filters such as higher filter order, temperature stability, and low cost. It is used in a range of applications such as cellular communication systems, fixed-wireless communication, GPS, broadband wireless networks, L-band satellite communication, and automotive in-vehicle systems.
