Surface Acoustic Wave (SAW) Filters, also known as acoustic wave filters are a type of electromagnetic filter that utilizes surface acoustic waves to filter out radio frequency signals. It is a sensitive and highly reliable type of filter and is particularly suited for use in mobile communication systems, where frequencies above 5 GHz are required. The B39881B9857P810S5 SAW Filter is designed for use in the 868 MHz ISM band used in many European countries. It covers the frequency range of 866.5-869.5 MHz, providing the necessary filtering and control of RF signals to achieve the desired data rate and output power.

The B39881B9857P810S5 SAW Filter achieves its performance by combining a metal foil and a piezoelectric crystal. The metal foil acts as a reflective reflector that is designed to reflect any incoming waves back into the piezoelectric crystal. The crystal then converts the reflected waves into electrical signals and passes them on to the intended receiver. The SAW filter also incorporates a resonance effect, meaning that a range of frequencies can be set to resonate at the desired frequency range.

The main application field of the B39881B9857P810S5 SAW filter is in mobile communication systems. The 868 MHz ISM band used in many European countries requires a high performance filter with low insertion loss. The B39881B9857P810S5 SAW Filter provides the necessary noise rejection and control of RF signals to maintain signal integrity at a given output power. It enables the device to achieve the desired data rate and output power levels with minimal interference.

In terms of its working principle, the B39881B98571P810S5 SAW Filter operates on a reflective resonance effect. The filter consists of two parts, namely the metal foil and the piezoelectric crystal. The foil acts as a reflector that is designed to reflect any incoming waves back into the piezoelectric crystal. The crystal then converts the reflected waves into electrical signals and passes them on to the intended receiver. This ensures that the desired frequencies are filtered out and the required data rate and output power levels are maintained.

Overall, the B39881B98571P810S5 SAW Filter is a highly effective and reliable filter that can be used to filter out radio frequencies for a range of applications. It is an ideal solution for mobile communication systems, as it is able to provide the necessary noise rejection and control of RF signals to achieve the desired data rates and output power levels. Furthermore, its reflective resonance effect ensures that the intended frequency range is filtered out for improved performance.
