The B39202-B8407-P810 is a SAW (Surface Acoustic Wave) filter manufactured by EPCOS, a TDK Group Company. SAW filters are widely used in RF (radio frequency) applications to selectively pass desired signals while rejecting unwanted frequencies. These filters are essential in modern communication systems for signal integrity and performance.

Applications

• Wireless Communication Systems: Used in wireless communication devices like mobile phones, Wi-Fi routers, and Bluetooth devices to filter out unwanted frequencies.
• Remote Control Systems: Employed in remote control devices to ensure only the intended control signals are received, reducing interference.
• Automotive Telematics: Utilized in automotive applications for filtering signals in keyless entry systems and other telematics devices.
• Television and Radio Receivers: Used to select the desired broadcast channel and reject interference from other signals.
• GPS Receivers: Employed to filter the GPS signal and improve accuracy.

Features

• SAW Technology: Utilizes surface acoustic waves to achieve precise filtering characteristics.
• Compact Size: Small form factor allows for use in space-constrained applications.
• Low Insertion Loss: Minimizes signal attenuation in the desired frequency band, improving signal strength.
