R574412610

Overview

The R574412610 is a single-pole six-throw (SP6T) terminated coaxial switch from the RAMSES series, manufactured by Radiall USA, Inc. It operates with SMA connectors and supports frequencies up to 18 GHz. The device features normally open configuration and is designed for termination applications. Key electrical parameters include a maximum insertion loss of 0.5 dB and minimum isolation of 60 dB at the test frequency. It requires a supply voltage range of 24V to 30V DC. The unit is packaged in bulk and is currently listed as an active component.

Feature Summary

• Single-pole six-throw (SP6T) switching architecture
• Terminated output design for direct load connection
• High isolation performance up to 60 dB
• Low insertion loss characteristics

Applications

• RF signal routing in communication systems
• Test and measurement equipment configurations
• Phased array antenna feed networks
• Automated testing setups requiring multiple path selection

Procurement Notes

Verify the specific ordering suffix to confirm the exact termination configuration and connector type before purchase. Ensure that the required supply voltage aligns with the 24V to 30V DC specification. Confirm availability status as distribution channels may vary. Cross-reference the datasheet for mechanical dimensions and mounting requirements to ensure compatibility with the intended PCB layout or chassis integration.

Selection Notes

Select this component when a high-frequency SP6T switch with integrated terminations is required. The RAMSES series offers robust performance for applications demanding low insertion loss and high isolation. Consider the SMA interface compatibility with existing system cabling. Evaluate the thermal management needs based on the operating temperature range and power handling capabilities specified in the official documentation.

Part Context

This part belongs to the RAMSES family of RF switches, which are known for their reliability in harsh environments. The R574412610 specifically addresses the need for multi-path switching with built-in terminations, simplifying system design by eliminating the need for external dummy loads. It complements other SPnT variants within the same product line offering different port counts.

Replacement Considerations

Consult the manufacturer's obsolescence notices for potential end-of-life status. Identify equivalent SP6T switches from the same RAMSES series or compatible families if pin-out and electrical specifications match. Verify that any substitute maintains the 18 GHz frequency range and 60 dB isolation requirement.
