• Remote control systems.
• ISM (Industrial, Scientific and Medical) band applications.
• Wireless sensor networks.
• Security systems and alarms.

Features

• Center Frequency: Specifically designed for operation around 868 MHz.
• Low Insertion Loss: Minimizes signal attenuation within the passband.
• High Attenuation: Effectively rejects signals outside the passband.
• Small Size: Compact design for integration into space-constrained applications.
• Surface Mount Device (SMD): Easy to assemble using standard surface mount techniques.

Benefits

• Improved Signal Quality: Filters out unwanted noise and interference, enhancing signal clarity.
• Increased Range: By reducing interference, the effective range of wireless communication systems can be extended.
• Reduced Interference: Prevents unwanted signals from disrupting the operation of the system.
• Simplified Design: Provides a pre-tuned filtering solution, reducing design complexity.
• Cost-Effective: Offers a competitive filtering solution compared to other technologies.

Additional Details

SAW filters utilize the piezoelectric effect of certain materials to create a mechanical wave on the surface of the device. This wave interacts with patterned electrodes, allowing for precise control over the frequency response. The TB0801A is typically used in the receiver section of a wireless communication system to filter out unwanted signals before they reach the sensitive receiver circuitry. It is important to match the impedance of the filter to the surrounding circuitry to minimize signal reflections and maximize performance.

Detailed specifications such as insertion loss, bandwidth, attenuation, and impedance can be found in the TAI-SAW TECHNOLOGY CO., LTD. datasheet for the TB0801A. Proper handling precautions should be taken when soldering the device to prevent damage from electrostatic discharge (ESD).
