TA1423A

Overview

The TA1423A is a Surface Acoustic Wave (SAW) filter manufactured by TST. It operates at a center frequency of 915 MHz with a bandwidth of 26 MHz and an insertion loss of 2.5 dB. The component utilizes a 5-SMD, no-lead package with dimensions of 1.40mm x 1.10mm. Designed for the North American unlicensed ISM band, it provides full-band filtering capabilities suitable for frequency meter reading applications.

Feature Summary

• Full band ISM band filtering designed for the North American unlicensed spectrum
• Small form factor surface mount construction for compact integration
• Optimized performance characteristics including low insertion loss

Applications

• Frequency meter reading circuits
• ISM band communication modules
• North American unlicensed device implementations

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and pinout configurations before finalizing design integration. Ensure compatibility with the target PCB footprint, specifically the SM1411-5PAD or equivalent 5-SMD no-lead layout. Cross-reference manufacturer specifications against application requirements to validate performance under operating conditions.

Selection Notes

Select this component when designing for the 915 MHz ISM band in North America. The 26 MHz bandwidth supports standard data rates for simple telemetry or metering applications. Consider the small physical footprint if space constraints are critical within the host device enclosure.

Part Context

This SAW filter belongs to TST's portfolio of RF components targeting industrial, scientific, and medical bands. It addresses the need for cost-effective, high-performance filtering in consumer and industrial electronics operating in the 900 MHz range without requiring complex external tuning networks.
