RF Directional Couplers Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm MSL level 1 classification for handling requirements. Ensure ordering suffix matches specific tape-and-reel specifications. Validate frequency range alignment with target GSM bands prior to integration. Check manufacturer lead times for accurate scheduling.

RF Directional Couplers Selection Notes

Select this component when GSM band coverage between 890MHz and 915MHz is required. Consider the 3W power rating for system power levels. Evaluate the 0805 footprint against available board space. Compare coupling coefficient accuracy needs against the ±1dB specification. Assess thermal management requirements relative to the 0.5dB insertion loss.

RF Directional Couplers Part Context

This part belongs to the CP0805 series of thin-film directional couplers from KYOCERA AVX. These components are engineered for RF signal conditioning and feedback applications. The series offers various coupling values and frequency ranges tailored for wireless communication standards. The CP0805A0902ESTR specifically targets GSM infrastructure and device implementations.

RF Directional Couplers Replacement Considerations

Consult official KYOCERA AVX documentation for direct substitutes. Verify identical frequency range, coupling coefficient, and power handling capabilities.
