TA915EC

Overview

The TA915EC is a Surface Acoustic Wave (SAW) filter manufactured by TST, designed for the 915 MHz Industrial, Scientific, and Medical (ISM) radio band. It operates within a center frequency of 915 MHz with a bandwidth of 26 MHz. Key electrical specifications include an insertion loss of 3.2 dB and attenuation levels of 23 dB to 24.5 dB. The component supports an input power level of 10 dBm and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF signal filtering in the ISM band
• Engineered for full-band coverage in North American unlicensed spectrum applications
• Constructed in a compact SMD package suitable for space-constrained designs

Applications

• Wireless communication systems requiring ISM band filtering
• RF front-end modules for industrial telemetry
• Scientific instrumentation utilizing 915 MHz frequencies
• Medical device communication interfaces

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with TST or authorized distributors before procurement. Confirm that the SMD3838-6P package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference part numbers to avoid confusion with similar models in the TST SAW filter lineup.

Selection Notes

Select this component when a dedicated SAW filter is required for the 915 MHz ISM band with low insertion loss. Consider the 3.8 x 3.8 mm package size for board layout constraints. Evaluate the 26 MHz bandwidth against your signal modulation requirements. Compare attenuation performance at out-of-band frequencies against alternative filter technologies such as ceramic or LC filters.

Part Context

This component belongs to TST's portfolio of surface acoustic wave filters targeting the ISM frequency bands. It represents an older generation design optimized for reliability in standard wireless applications. The product line includes various form factors, but this specific model utilizes a small outline no-lead package for surface mounting.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult TST technical support for direct replacements or cross-references. Verify compatibility with existing circuit impedance and matching networks if substituting with components from other manufacturers.
