R574F03300

RF Switches Overview

The R574F03300 is a terminated coaxial switch from the Ramses series, manufactured by Radiall. It features an SP3T circuit configuration with SMA connectors and operates up to 26.5 GHz. The device utilizes a normally open latching mechanism powered by 28Vdc via pin terminals. Designed for general RF applications, it maintains a 50 Ohm impedance and functions within a temperature range of -40°C to 85°C.

RF Switches Feature Summary

• Terminated Ramses design with SMA interface
• SP3T circuit topology for signal routing
• Normally open latching operation mode
• High-frequency performance up to 26.5 GHz

RF Switches Applications

• General purpose RF signal switching
• Test and measurement instrumentation
• Telecommunications equipment

RF Switches Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply chain conditions may vary. Confirm that the specific ordering suffix matches the required connector type and voltage specifications. Ensure compliance with relevant environmental regulations such as RoHS before finalizing procurement orders.

RF Switches Selection Notes

Select this component when a high-frequency SP3T switch with SMA connectors is required. The 26.5 GHz frequency range supports demanding RF applications. The normally open latching feature provides power-efficient state retention. Verify that the 28Vdc control voltage aligns with the system's power supply capabilities.

RF Switches Part Context

This part belongs to the Ramses family of terminated coaxial switches, designed for robust RF performance. The R574G13345 is a similar SP3T variant but operates at a lower frequency of 18 GHz. Both share the terminated Ramses architecture but differ in frequency specifications and connector ratings.

RF Switches Replacement Considerations

The R574G13345 serves as a functional substitute for lower-frequency requirements up to 18 GHz. Ensure that the replacement meets the necessary isolation and insertion loss specifications for the specific application environment.
