SAW Filters

SAW (Surface Acoustic Wave) Filters are frequency selective filtering devices utilizing acoustic waves running over a piezoelectric substrate. They are deployed in a wide variety of applications for signal conditioning in order to eliminate unwanted frequencies or to retrieve desired frequencies. The general principle of the B39521B5106U410 SAW filter consists of an input section designed to capture the input signal, a series of interdigital transducers embedded in the surface of the substrate, and an output section designed to convert the frequency-selective output signal to a low-impedance output.

Application Field

The B39521B5106U410 SAW filter is used in a variety of applications ranging from radio communication, consumer electronics, to general instrumentation. This versatile device is suitable for use in cellular radios, as a RF filter in Envelope Tracking circuits, and also as a replacement for bulky passive components in mixers and amplifiers. This filter can also be used to correct the harmonic distortion in narrow-band signal receivers.

Working Principle

When an electromagnetic signal is sent to the initial section of the B39521B5106U410 SAW filter, it is in the form of an acoustic wave at the end of the series of interdigital transducers within the substrate. This acoustic wave energy is then received by the output section of the SAW filter, consisting of the interdigital transducer and a parasitic element that acts as a mechanical load. The output section of the B39521B5106U410 SAW filter is designed to work as a low-noise amplifier, converting the acoustic wave energy into an electrical signal. The processed signal can be selected according to the desired frequency, allowing for high signal integrity and noise elimination. The signal processing capabilities of the B39521B5106U410 SAW filter make it an ideal device for applications such as radio communications, instrumentation, and consumer electronics.
