TA1982A

Overview

The TA1982A is a radio frequency surface acoustic wave (SAW) bandpass filter manufactured by TST. It operates at a center frequency of 2492 MHz with a bandwidth of 25 MHz. The device typically exhibits an insertion loss of 2.8 dB. It is housed in a compact 6-SMD, no-lead package with a maximum height of 0.055 inches (1.40 mm). Designed for wireless applications, this component provides signal filtering capabilities suitable for integration into mobile communication systems and other RF circuits requiring precise frequency selection.

Feature Summary

• Utilizes surface acoustic wave technology for efficient radio frequency signal processing
• Provides bandpass filtering characteristics centered at 2492 MHz
• Designed for surface mount assembly using a leadless SMD package

Applications

• Wireless communication devices
• Mobile phone baseband and RF front-end modules
• GPS receiver circuits

Procurement Notes

Verify the specific datasheet version from Tai-Saw Technology Co., Ltd. to confirm electrical tolerances and pinout configurations. Ensure compatibility with the target PCB footprint, specifically the 6-SMD no-lead package dimensions. Cross-reference the center frequency and bandwidth requirements against the system design specifications before finalizing procurement orders.

Selection Notes

Select this component when a SAW filter is required for the 2.4 GHz ISM band or similar wireless standards. Consider the 25 MHz bandwidth and 2.8 dB insertion loss against system link budget requirements. Evaluate the 6-pin surface mount form factor for space-constrained designs compared to larger through-hole alternatives.

Part Context

Tai-Saw Technology (TST) specializes in RF SAW filters for telecommunications. The TA series includes various models for different frequency bands.
