TA1924A

Overview

The TST TA1924A is a Surface Acoustic Wave (SAW) RF filter designed for high-frequency signal processing applications. It operates at a center frequency of 1.1918 GHz with a bandwidth of 55 MHz and provides an insertion loss of 4 dB. The component is housed in an 8-SMD, No Lead package, suitable for surface-mount assembly. It supports an operating temperature range from -40°C to +85°C, ensuring reliability in various environmental conditions.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF filtering
• Optimized for GPS, GLONASS, GALILEO, and Beidou satellite navigation systems
• Designed for integration into base stations and mobile communication devices

Applications

• GPS receiver modules
• GLONASS navigation systems
• GALILEO positioning units
• Beidou satellite receivers
• Base station equipment

Procurement Notes

Verify the specific datasheet version to confirm pinout compatibility and thermal specifications before integration. Ensure that the 8-SMD no-lead package matches your PCB footprint design. Cross-reference the 1.1918 GHz center frequency requirement with your system's local oscillator settings to guarantee proper signal filtering performance.

Selection Notes

Select this component when a narrowband SAW filter is required for L-band GNSS signals. The 55 MHz bandwidth suits standard navigation frequencies. Consider the 8-SMD package size for space-constrained designs. Verify that the 4 dB insertion loss meets your link budget requirements for low-noise amplifier inputs.

Part Context

This part belongs to the TST TA series of RF SAW filters, which are engineered for global navigation satellite systems. The series includes variants optimized for different regional standards such as GPS, GLONASS, and Galileo. These components are widely used in consumer electronics and professional positioning hardware requiring high selectivity and compact form factors.

Replacement Considerations

Check for direct substitutes within the TST TA series that share the same 1.1918 GHz center frequency and 8-SMD package. Ensure any replacement maintains the 55 MHz bandwidth and -40°C to +85°C operating range. Verify pin-to-pin compatibility if swapping with other manufacturers' SAW filters.
