TA0992A

Overview

The TA0992A is a Surface Acoustic Wave (SAW) filter manufactured by TST, designed for wireless RF applications. It operates at a center frequency of 902.5 MHz with a bandwidth of 25 MHz. The device features an insertion loss of 3.3 dB and provides attenuation levels of 54 dB, 28 dB, 55 dB, and 30 dB at specified frequencies. It is housed in a compact 6-SMD, No Lead package with dimensions of 3.0 x 3.0 mm. The component supports an operating temperature range from -25°C to +75°C.

Feature Summary

• Surface Acoustic Wave technology for RF signal filtering
• Rail-to-rail input/output capability not applicable; SAW filter topology
• Compact SMD packaging for surface mount assembly

Applications

• Wireless RF communication systems
• Industrial, Scientific, and Medical (ISM) band devices
• Remote control and telemetry equipment

Procurement Notes

Verify the specific datasheet version from Tai-Saw Technology Co., Ltd. or authorized distributors to confirm exact attenuation curves and pinout configurations. Ensure the 6-SMD no-lead package matches the PCB footprint requirements. Check for RoHS compliance status if required by the manufacturing process. Confirm the operating temperature range aligns with the environmental conditions of the final application.

Selection Notes

Select this component when a narrow-band filter centered at 902.5 MHz is required for ISM band applications. The low insertion loss of 3.3 dB helps maintain signal integrity. Consider the 25 MHz bandwidth relative to the channel spacing requirements. The small 3.0 x 3.0 mm package is suitable for space-constrained designs. Compare performance against other SAW filters if higher attenuation or different center frequencies are needed.

Part Context

The TA0992A belongs to the family of SAW filters produced by Tai-Saw Technology. These components are distinct from operational amplifiers like the TSV992A, serving purely as passive RF filtering elements. The product line focuses on high-frequency signal processing for wireless communications.
