TA0700A

Overview

The TST TA0700A is a Surface Acoustic Wave (SAW) band-pass filter designed for wireless applications. It operates at a center frequency of 2.25 GHz with a bandwidth of 100 MHz. The device features an insertion loss of 4.5 dB and provides attenuation levels of 28 dB and 32.5 dB. It is housed in a compact SMD3030 package, specifically a 6-SMD, No Lead configuration with dimensions of 3.00mm x 3.00mm and a maximum height of 1.40mm. The component supports an operating temperature range from -20°C to +70°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Optimized for high-frequency wireless communication bands
• Designed for surface mount assembly in space-constrained environments

Applications

• Wireless communication systems
• Mobile phone base stations
• GPS receivers

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and pinout configurations before integration. Ensure that the supply chain source is authorized to guarantee component authenticity and traceability. Check for any recent manufacturing changes or obsolescence notices directly from Tai-Saw Technology Co. Ltd. to avoid compatibility issues in production lines.

Selection Notes

Select this component when a narrow 100 MHz bandwidth is required around the 2.25 GHz center frequency. The low profile SMD package suits automated surface mounting processes. Consider the thermal operating range limits during system design to ensure reliability under varying environmental conditions without requiring additional heating or cooling mechanisms.

Part Context

Tai-Saw Technology specializes in SAW components, including filters and resonators, for consumer electronics and telecommunications. The TA0700A belongs to their RF filter portfolio, targeting markets such as satellite digital broadcasting and wireless local area networks. This product line supports the miniaturization trends in modern mobile devices and infrastructure equipment.

Replacement Considerations

Cross-reference with other 2.25 GHz SAW filters from manufacturers like Murata or Skyworks if sourcing constraints exist. Verify that substitute parts match the exact 6-SMD footprint and electrical specifications to maintain circuit performance without redesigning the PCB layout.
