The TA0819A is a SAW (Surface Acoustic Wave) filter manufactured by TAI-SAW TECHNOLOGY CO., LTD. It is designed for use in RF (Radio Frequency) applications to selectively pass or reject signals within a specific frequency band.

Applications

• Wireless communication systems
• Cellular base stations
• Remote controls
• Wireless sensors
• GPS receivers
• RFID systems

Features

• Low insertion loss
• High rejection
• Sharp roll-off
• Small size
• Surface-mount package
• High reliability

Benefits

• Minimal signal attenuation in the passband due to low insertion loss.
• Effective filtering of unwanted signals due to high rejection in the stopband.
• Precise frequency selectivity with sharp roll-off characteristics.
• Reduced board space requirements with small size.
• Easy integration into printed circuit boards with surface-mount package.
• Consistent performance over a long lifespan due to high reliability.

Additional Details

The TA0819A is typically designed for a specific center frequency and bandwidth, depending on the application. It features a small footprint and low profile, making it suitable for compact wireless devices. The SAW filter technology provides excellent frequency selectivity and stable performance over temperature variations. Specific parameters, such as the center frequency, bandwidth, insertion loss, and rejection, need to be verified with the product's datasheet for the particular application. It ensures effective signal filtering in wireless communication systems.
