RF Switches Procurement Notes

Verify the specific suffix PIN against official MACOM documentation to confirm package type and termination style. Ensure compatibility with required control voltage levels (-8 V to -4.75 V) before integration. Confirm RoHS compliance status through current manufacturer declarations as regulatory requirements may change over time.

RF Switches Selection Notes

Select this component when a single-pole single-throw configuration is required up to 3 GHz. The integrated driver simplifies board design by reducing external control circuitry needs. Consider the 16-lead ceramic package for thermal management and reliability in high-frequency applications requiring low insertion loss.

RF Switches Part Context

This part belongs to the MACOM family of GaAs MMIC switches designed for wireless and RF integrated circuits. It serves as a specialized solution for applications demanding precise signal path control with minimal signal degradation across broad frequency bands.

RF Switches Replacement Considerations

Consult official MACOM substitution guides for verified equivalents. Generic replacements may not match the integrated driver architecture or specific impedance characteristics.
