R573402405

RF Switches Overview

The R573402405 is a SP4T coaxial switch from the Ramses series by Radiall. It operates within a frequency range of DC to 18GHz with a 50-ohm impedance. The device features normally open contacts and utilizes a 12Vdc control voltage via a D-sub connector interface. Key electrical specifications include a maximum insertion loss of 0.5dB and a minimum isolation of 60dB. It supports BCD TTL logic for channel selection.

RF Switches Feature Summary

• SP4T topology for signal routing
• Broadband operation up to 18GHz
• Normally open contact configuration
• D-sub connector control interface

RF Switches Applications

RF Switches Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct factory channels. Confirm RoHS compliance status and specific datasheet revisions prior to ordering. Ensure storage conditions meet moisture sensitivity level requirements. Validate that the D-sub connector mating interfaces align with system design constraints before finalizing procurement.

RF Switches Selection Notes

Select this model when high-frequency performance up to 18GHz is required alongside low insertion loss characteristics. The SP4T configuration suits applications needing one input routed to four outputs. Verify that the 12Vdc control voltage and D-sub connector form factor are compatible with existing board layouts and power supplies.

RF Switches Part Context

This component belongs to the Ramses family of coaxial switches, designed for demanding RF environments. The series emphasizes reliability and consistent electrical performance across wide bandwidths. The R573402405 variant specifically addresses SP4T switching needs with SMA connectors.

RF Switches Replacement Considerations

Cross-reference with other Ramses series models for similar SP4T configurations. Verify pinout compatibility and control logic differences when substituting. Ensure replacement parts maintain the same 18GHz frequency range and 60dB isolation specifications.
