TA0222A

Overview

The TA0222A is a Surface Acoustic Wave (SAW) filter manufactured by TST, designed for wireless RF applications. It operates at a center frequency of 2442 MHz with a bandwidth of 55 MHz and an insertion loss of 1.9 dB. The component is housed in a compact 3.0x3.0 mm SMD package with six leads. It supports an operating temperature range from -20°C to +70°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

• Utilizes surface acoustic wave technology for RF signal filtering
• Automotive-grade reliability compliant with AEC-Q200 standards
• Compact surface-mount design suitable for space-constrained devices

Applications

• Satellite digital broadcasting systems
• Mobile phone and base station communications
• Wireless local area networks (WLAN)
• GPS navigation modules
• Wireless Bluetooth devices

Procurement Notes

Verify the specific datasheet revision and package variant when sourcing, as manufacturer documentation may list multiple pin configurations or tolerance levels for this part number. Confirm that the supplier provides official TST documentation rather than third-party interpretations. Ensure the procurement channel is authorized to guarantee component authenticity and traceability for automotive or high-reliability applications.

Selection Notes

Select the TA0222A when a 2442 MHz center frequency and 55 MHz bandwidth are required for SAW filtering. Consider its AEC-Q200 qualification if the application involves automotive environments. Compare its 1.9 dB insertion loss against other options if low-loss performance is critical. Ensure the 3.0x3.0 mm footprint fits the PCB layout constraints.
