Standing acoustic wave (SAW) filters are electronic parts used to select desired frequencies within an antenna’s radio-frequency (RF) signal input. TheB39192B9428K610W99 SAW filter is designed for use in mobile communication systems, such as global system for mobile communications (GSM) and multiple access systems (MAS). It is a high-power filter able to handle signals up to 2 Watts, which makes it suitable for powerful mobile communications signals.

SAW filters operate by propagating acoustic waves within a piezoelectric substrate, such as quartz crystal or lithium niobate. The propagation of acoustic waves enables the selective filtering of desired frequency components while rejecting undesired components. This is accomplished by changing the acoustic phase, amplitude, or both, on the acoustic wave energy, so that a desired frequency component is allowed to pass in the pass-band while signals outside that band are rejected.

When a signal is passed through the SAW filter, it is first split into two paths. One path enters the input transducer, while the other enters the output transducer. Both paths travel through the surface of the filter and pass through the piezoelectric substrate, and finally reach the output transducer. The input and output transducers convert electrical signals to mechanical waves, and vice versa. The acoustic wave energy interacts with the piezoelectric substrate in such a way that signal components of different frequencies have different amplitudes and phases at the output transducer.

The B39192B9428K610W99 SAW filter is designed to pass signals within a given frequency range, while rejecting signals outside that range. The filter\'s performance is characterized by its pass-band center frequency, pass-band width, and pass-band loss. The center frequency is the frequency at which the highest signal-to-noise ratio is attainable. The pass-band width is the frequency range around the center frequency in which signals are allowed to pass. The pass-band loss is the amount of signal energy lost during the filtering process. These parameters can be adjusted to meet the desired performance needs.

In addition to mobile communications, the B39192B9428K610W99 SAW filter is also used in other applications such as automotive audio, home entertainment systems, and wireless communication systems. The filter’s wide operating frequency range and high power rating makes it suitable for use in high-power communication systems. Furthermore, its low insertion loss makes it an efficient and cost-effective solution for filtering applications.

The B39192B9428K610W99 SAW filter combines the advantages of high-power capability, low insertion loss, wide operating frequency range, and excellent performance in order to provide a robust and reliable RF filtering solution. Its wide application field in mobile communications, automotive audio, home entertainment systems, and wireless communications makes it an ideal filtering choice for demanding applications.
