TA1865A

Overview

The TST TA1865A is a Surface Acoustic Wave (SAW) filter designed for wireless RF applications. It operates at a center frequency of 725.5 MHz with a bandwidth of 45 MHz, covering the range from 703 MHz to 748 MHz. The component exhibits a typical insertion loss of 4.5 dB and is housed in a 6-SMD, no-lead package.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF signal filtering
• Optimized for low insertion loss performance
• Designed for compact surface-mount integration

Applications

• LTE Band 13 systems
• LTE Band 20 systems
• General wireless communication equipment

Procurement Notes

Verify the specific datasheet version and approval status before procurement. Confirm that the 6-SMD no-lead package matches the target PCB footprint requirements. Ensure the operating temperature range aligns with the system environment specifications to guarantee reliable performance in the final assembly.

Selection Notes

Select this component when a SAW filter is required for the 703-748 MHz frequency range. Consider the 4.5 dB insertion loss specification against system link budget requirements. Evaluate the 6-SMD package size constraints relative to available board space and manufacturing capabilities for leadless surface mount devices.
