TA1923A

Overview

The TA1923A is a Surface Acoustic Wave (SAW) filter manufactured by TST Semiconductor. It operates at a center frequency of 1587.1 MHz, suitable for GNSS L2C/G2 band applications. The device features an insertion loss of 2.4 dB and a bandwidth of 55 MHz. It is housed in a compact SMD 3030-6P package with dimensions of 3.0 x 3.0 mm. The component is RoHS compliant and currently active.

Feature Summary

• Integrated SAW filter technology for signal processing
• Compact surface-mount design for space-constrained PCBs
• RoHS compliant construction

Applications

• GNSS L2C/G2 band filtering
• GPS receiver front-end modules
• Multi-constellation navigation systems

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as standard lead times may vary by distributor. Confirm that the SMD 3030-6P package matches your board layout requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the component status is listed as active before finalizing procurement plans.

Selection Notes

Select this component when a 1587.1 MHz center frequency is required for GNSS applications. The 55 MHz bandwidth supports L2C/G2 signals. The 3.0x3.0 mm footprint is critical for dense layouts. Compare insertion loss specifications against system noise budget requirements. Ensure compatibility with automated pick-and-place equipment for the 6-pin SMD package.
