TA2629A

Overview

The TST TA2629A is a surface acoustic wave (SAW) filter designed for pager communication systems operating at a center frequency of 836.5MHz. It features a bandwidth of 25MHz and operates within a temperature range of -30°C to +85°C. The component provides attenuation values ranging from 13dB to 45dB across various frequencies, with an impedance of 50Ω. Packaged in a compact 5-SMD, No Lead format measuring 1.40mm x 1.10mm, it ensures precise RF signal filtering for legacy wireless connectivity applications.

Feature Summary

• Engineered specifically for pager communication systems
• Provides precise RF signal filtering at 836.5MHz
• Compact 5-SMD no-lead package design

Applications

• Pager communication systems
• RF signal filtering in wireless connectivity devices
• Legacy mobile communication hardware

Procurement Notes

Verify the specific manufacturer part number TA2629A against official TST documentation to confirm compatibility with your system requirements. Ensure that the operating temperature range of -30°C to +85°C meets your environmental specifications. Confirm the 5-SMD package dimensions align with your PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing for pager bands around 836.5MHz requiring SAW filter technology. Consider the 25MHz bandwidth and 50Ω impedance for matching network design. Evaluate the thermal performance limits if the device will operate in extreme environments outside the specified -30°C to +85°C range.

Part Context

TST, or Jia Shuo Technology Co., Ltd., specializes in surface acoustic wave components including RF SAW filters and resonators. The TA2629A belongs to their portfolio of wireless connectivity products, targeting niche markets such as paging systems where high-frequency precision and small form factors are critical for reliable signal transmission.

Replacement Considerations

No public confirmed substitute part numbers are available for the TST TA2629A. Verify electrical parameters carefully if considering alternatives from other manufacturers, as SAW filter characteristics are highly specific to frequency and attenuation profiles.
