R573413010

Overview

The Radiall R573413010 is an SP10T coaxial switch from the RAMSES series, designed for high-frequency applications up to 18 GHz. It features SMA connectors and a normally open configuration with positive common logic. The device utilizes 28Vdc control voltage and TTL diode input signals. Key electrical specifications include low insertion loss and high isolation, ensuring signal integrity in complex RF routing systems. The unit is housed in a compact form factor suitable for dense panel mounting.

Feature Summary

• SP10T single-pole ten-throw switching architecture
• Operates at frequencies up to 18 GHz
• Normally open state with positive common logic
• Compatible with 28Vdc control and TTL inputs

Applications

• Test and measurement instrumentation
• Aerospace and defense radar systems
• Telecommunications base stations
• Satellite communication ground equipment

Procurement Notes

Verify the specific datasheet revision and mechanical drawing compatibility before integration. Confirm that the 28Vdc control interface aligns with existing system logic levels. Ensure thermal management requirements are met within the operating temperature range. Cross-reference the SMA connector gender and mating constraints with adjacent hardware components to prevent assembly errors during installation.

Selection Notes

Select this component when a high-isolation, multi-port switching solution is required for frequencies reaching 18 GHz. The SP10T topology allows routing a single signal path to one of ten outputs efficiently. Consider the normally open default state and positive common logic for fail-safe design requirements. Evaluate the physical footprint against available panel space in constrained aerospace or military enclosures.

Part Context

This part belongs to the RAMSES family of coaxial switches by Radiall USA, Inc., known for robust performance in harsh environments. The series offers various throw configurations and frequency ranges, with the R573413010 specifically addressing high-channel-count needs. It complements other RF components in signal distribution networks where reliable, repeatable switching is critical for system accuracy.

Replacement Considerations

Direct substitutes may include other SP10T SMA switches from Radiall such as the R573413025, though frequency and control interface differences must be verified. Alternative manufacturers offering similar RAMSES-compatible units should be evaluated for pinout and electrical parameter equivalence. Ensure any replacement maintains the 18 GHz operational limit and 28Vdc control compatibility.
