R574323840

Overview

The R574323840 is a general-purpose RF switch manufactured by Radiall USA, Inc. It features an SP8T configuration with SMA connectors and operates within a frequency range of 0 Hz to 3 GHz. The component maintains a 50 Ohm impedance and utilizes a latching mechanism powered by 28 VDC. Key electrical specifications include a maximum insertion loss of 0.2 dB and a non-illuminated design. It is constructed for surface mount applications using solder terminals.

Feature Summary

• SP8T switching topology for multi-path signal routing
• SMA connector interface for standardized RF connections
• Latching mechanism for stable state retention without continuous power
• Surface mount construction for PCB integration

Applications

• General purpose RF signal routing in communication systems
• Test and measurement equipment requiring multi-port switching
• Wireless infrastructure components operating below 3 GHz

Procurement Notes

Verify the specific datasheet version for the R574323840 to confirm exact mechanical dimensions and pinout configurations before finalizing designs. Ensure compatibility with the required 28 VDC control voltage levels. Cross-reference manufacturer documentation for any updates regarding material composition or environmental compliance standards such as RoHS status.

Selection Notes

Select this component when an eight-way single-pole switching solution is required for frequencies up to 3 GHz. The low insertion loss of 0.2 dB makes it suitable for sensitive signal paths. Consider the SMA interface type and surface mount package style against available board space and connector availability requirements in the system architecture.

Part Context

This part belongs to the Ramses series of coaxial switches from Radiall. The series typically offers various pole counts and frequency ranges. The R574323840 specifically addresses the need for high-channel-count switching at lower microwave frequencies compared to higher-frequency variants in the same product family.

Replacement Considerations

Check for direct substitutes within the Ramses series that offer identical SP8T configurations and SMA interfaces. Verify that alternative parts match the 3 GHz frequency limit and 28 VDC latching voltage requirements to ensure functional equivalence in existing circuits.
