Surface acoustic wave (SAW) filters are used in nearly all modern wideband communication systems. The B39458M3951M100S1 acoustic wave filter is one of the most widely used devices in the field of communication due to its high performance, small size, low power consumption and low cost. It is suitable for many different applications, such as mobile communication, military communication, avionics communication, digital broadcasting, and wireless data transmission.

The B39458M3951M100S1 is a three-port SAW filter that utilizes a planar dielectric waveguide loaded with a thin zinc oxide (ZnO) surface acoustic wave filter substrate. The filter substrate consists of transverse acoustic wave transducers (TACTs) which act as transmitters and receivers, and two gap gratings that produce Bragg mirrors which act as transceivers. The transducers are placed on the substrate in a triangle pattern, which enables three different transmit directions.

The working principle of the B39458M3951M100S1 SAW filter is based on the phenomenon of acoustic wave propagation. When a voltage is applied to the TACTs, they generate acoustic waves, which propagate along the surface of the substrate and form standing waves in the gaps between the gratings. These standing waves act as filters, allowing only desired frequencies to pass through. This ensures that only the desired signal is received and all other frequencies are attenuated.

The B39458M3951M100S1 SAW filter is well suited for use in multiple frequency applications. This is because the filter has the ability to switch the frequency of operation electronically. This makes it ideal for applications requiring quick frequency changes or where different frequencies must be selected depending on the situation. It is also capable of providing high levels of selectivity and rejection, with a stop-band attenuation of more than 70 dB. In addition, the device has excellent temperature stability, as well as low power consumption and cost.

The B39458M3951M100S1 SAW filter is a versatile and reliable device suitable for a wide range of applications. It is commonly used in mobile communications and digital broadcasting, but can also be used in avionics systems and wireless data transmission. Its small size, low power consumption and high performance make it an ideal choice for many applications where reliability and performance are essential.
