R585443300

RF Switches Overview

The R585443300 is a single-pole double-throw (SPDT) coaxial switch manufactured by Radiall USA, Inc. It operates within the Ramses series and utilizes an SMA interface with a characteristic impedance of 50 Ohms. The device supports frequencies up to 18 GHz and features a normally open configuration. It is designed for termination applications and includes internal loads. The unit requires a 28Vdc control voltage and incorporates TTL diodes for operation. Indicators are present on the assembly, which is packaged in bulk.

RF Switches Feature Summary

• Single-pole double-throw switching architecture
• SMA interface supporting frequencies up to 18 GHz
• Normally open state with integrated internal loads
• 28Vdc control voltage with TTL diode logic

RF Switches Applications

• RF signal routing in microwave test systems
• Terminated load configurations in communication equipment
• High-frequency switching in aerospace environments

RF Switches Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific suffix matches the required electrical specifications, particularly regarding the 28Vdc control voltage and TTL diode requirements. Ensure the package type aligns with system integration needs. Request current availability status directly from the supplier as stock levels fluctuate.

RF Switches Selection Notes

Select this component when a normally open SPDT switch is required for frequencies reaching 18 GHz. The 28Vdc control requirement must be compatible with the host system's power supply. Verify that the SMA interface and 50 Ohm impedance match the circuit design. Consider the presence of indicators if visual status feedback is necessary for the application.

RF Switches Part Context

This part belongs to the Ramses series of coaxial switches from Radiall, designed for demanding RF applications. The series is known for reliability in space and military markets. The R585443300 variant specifically integrates termination loads and indicator functionality, distinguishing it from standard unindicated models within the same family.

RF Switches Replacement Considerations

Check for direct substitutes within the R5854 series that may differ only in control voltage or indicator presence. Verify mechanical compatibility and pinout definitions before substituting. Ensure any alternative maintains the 18 GHz frequency limit and 50 Ohm impedance characteristics.
