TA2630A

Overview

The TA2630A is a Surface Acoustic Wave (SAW) filter manufactured by TST, designed for radio frequency applications. It operates at a center frequency of 1.74 GHz and features a bandwidth of 60 MHz with an insertion loss of 1.5 dB. The component is housed in a compact 5-SMD, no-lead package suitable for surface mount assembly. It functions as a bandpass filter intended for frequency pager RF circuits. The device supports an operating temperature range from -30°C to +85°C and requires a 50Ω source and load impedance for optimal performance.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF signal filtering
• Optimized for 1.74 GHz frequency pager applications
• Compact 5-SMD leadless package design
• Operates within extended industrial temperature ranges

Applications

• Frequency pager RF front-end circuits
• Radio frequency signal processing modules
• Wireless communication receiver stages

Procurement Notes

Verify the specific datasheet version to confirm exact pinout configurations and recommended soldering profiles. Ensure that the receiving circuit provides the required 50Ω single-ended source and load impedances for accurate electrical performance. Confirm that the operating environment remains within the specified -30°C to +85°C range. As an electrostatic sensitive device, appropriate handling precautions must be observed during installation and testing procedures.

Selection Notes

Select this component when a narrowband filter is required specifically for the 1.74 GHz pager frequency band. The 60 MHz bandwidth and low insertion loss make it suitable for applications demanding high selectivity with minimal signal attenuation. The SMD package facilitates automated assembly processes. Engineers should verify compatibility with existing PCB layout constraints and thermal management requirements before integration into the final design.
