R574422445

RF Switches Overview

The Radiall R574422445 is an SP4T coaxial switch from the Ramses series, designed for high-frequency applications up to 18 GHz. It features a terminated design with SMA connectors and utilizes a latching mechanism powered by 12Vdc. The component employs a D-sub connector interface and operates with positive common polarity. This configuration ensures reliable signal routing in demanding RF environments while maintaining precise impedance characteristics.

RF Switches Feature Summary

• SP4T switching topology for multi-path signal distribution
• Terminated construction ensuring stable impedance matching
• Latching mechanical action for state retention without continuous power
• SMA interface compatibility for standard RF integration

RF Switches Applications

• Test and measurement instrumentation requiring signal routing
• Telecommunications base station antenna switching systems
• Aerospace and defense radar signal processing chains
• Automotive radar sensor development and validation setups

RF Switches Procurement Notes

Verify the specific ordering suffix against the official Radiall datasheet to confirm electrical parameters and connector type. Ensure the 12Vdc latching requirement aligns with system power architecture. Confirm availability status as supply conditions may vary. Request the latest technical data sheet directly from the manufacturer or authorized distributors to validate compliance with current specifications before procurement.

RF Switches Selection Notes

Select this component when an SP4T configuration is required within the 18 GHz frequency range. The latching feature eliminates the need for continuous holding voltage, reducing power consumption compared to non-latching alternatives. Verify that the SMA connector type matches the existing PCB or cable assembly requirements. Ensure the positive common polarity specification is compatible with the control logic of the driving circuitry.

RF Switches Part Context

This part belongs to the Ramses series of coaxial switches manufactured by Radiall USA, Inc. The series is characterized by robust construction suitable for harsh environments. The R574422445 variant specifically integrates latching functionality and SMA interfaces, distinguishing it from other models in the family that may use different connector types or non-latching mechanisms.

RF Switches Replacement Considerations

Consult the official Radiall cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the SP4T topology, 18 GHz frequency limit, and SMA interface. Verify that the latching mechanism and 12Vdc control voltage are identical to prevent functional mismatches in the host system.
