RF Switches Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revisions and RoHS compliance status prior to integration. Ensure supply chain documentation matches the specific part number suffixes to guarantee electrical parameter consistency and long-term availability support.

RF Switches Selection Notes

Select this component when DPDT switching at frequencies up to 3GHz is required. The latching feature reduces power consumption during steady states compared to non-latching alternatives. Verify that the SMA connector interface aligns with existing PCB layout constraints and that the 24V-30V supply voltage is compatible with the system power architecture.

RF Switches Part Context

This part belongs to the RAMSES series of high-performance RF switches designed for critical applications. The series emphasizes low insertion loss and high isolation, making it suitable for complex signal routing tasks where signal fidelity is paramount. The module format simplifies integration into larger RF subsystems.

RF Switches Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains identical DPDT topology, 3GHz frequency limit, and SMA connector compatibility. Verify that alternative parts meet the same 80dB isolation and 0.2dB insertion loss specifications.
