The TA1004A, manufactured by TAI-SAW TECHNOLOGY CO., LTD., is a surface acoustic wave (SAW) filter designed for intermediate frequency (IF) filtering in television (TV) and other video applications. This filter provides excellent selectivity and low insertion loss, ensuring high-quality signal processing.

Applications:

• Television (TV) Receivers: Used for IF filtering to select the desired channel and reject unwanted signals.
• Set-Top Boxes (STBs): Employed in STBs to filter the IF signal before demodulation.
• Video Recorders (VCRs): Utilized in VCRs to improve the quality of the recorded signal.
• Cable Modems: Used for filtering signals in cable modem applications.
• Satellite Receivers: Found in satellite receivers to filter the IF signal.

Features:

• SAW Filter Technology: Provides excellent selectivity and low insertion loss.
• Compact Surface Mount Package: Facilitates easy assembly and integration into compact circuit designs.
• High Attenuation: Effectively rejects unwanted signals and noise.
• Stable Performance: Maintains stable performance over a wide range of operating conditions.
• RoHS Compliant: Meets environmental regulations, ensuring compliance with international standards.

Benefits:

• Improved Signal Quality: Provides clean and clear signal reception by filtering out unwanted noise and interference.
• Enhanced Selectivity: Effectively selects the desired channel and rejects adjacent channel interference.
• Compact Design: Surface mount package allows for integration into small form-factor devices.
• Reliable Performance: SAW filter technology ensures stable and consistent performance.
• Easy Integration: Designed for easy assembly and integration into various video and communication systems.

Technical Specifications:

The TA1004A typically operates at a center frequency around 38.9 MHz or similar IF frequencies used in TV systems. The insertion loss is typically around 3 dB to 5 dB. The filter provides high attenuation at frequencies outside the passband, ensuring excellent channel selectivity. The device is available in a small surface mount package, such as a SMD package. Its stable performance and compact size make it a preferred choice for designers seeking to optimize the performance of their video receiver circuits.
