R577812107

RF Switches Overview

The R577812107 is a DPDT coaxial switch from the Ramses series, manufactured by Radiall. It operates with an SMA2.9 interface and supports a frequency range of 0Hz to 40GHz. The device utilizes a failsafe control mechanism powered by 12Vdc. Signal connections are managed via TTL Diodes, while control inputs utilize a D-sub connector. This component is designed for high-reliability RF switching applications requiring precise signal routing within the specified bandwidth.

RF Switches Feature Summary

• DPDT topology with 0Hz to 40GHz operational bandwidth
• Failsafe control mechanism ensuring defined state retention
• SMA2.9 interface for signal connectivity
• D-sub connector for control input management

RF Switches Applications

• High-frequency RF signal routing in test equipment
• Aerospace and defense communication systems
• Automated measurement setups requiring reliable switching
• Broadband instrumentation signal distribution

RF Switches Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply conditions may vary. Confirm that the specific configuration matches the required failsafe operation and D-sub control interface. Ensure compatibility with existing 12Vdc power supplies and TTL logic levels before integration into system designs.

RF Switches Selection Notes

Select this model when a DPDT configuration is required for frequencies up to 40GHz. The failsafe feature is critical for applications where maintaining a known signal path state during power loss is necessary. Verify that the SMA2.9 interface aligns with system cabling requirements and that the D-sub control interface fits the available panel space.

RF Switches Part Context

This component belongs to the Ramses series of coaxial switches, which are engineered for demanding environments. The series typically offers high reliability and performance across broad frequency ranges. The R577812107 variant specifically integrates failsafe functionality and digital control interfaces suitable for complex RF infrastructure.

RF Switches Replacement Considerations

Consult official documentation for direct substitutes within the Ramses series. Verify that any alternative part maintains the same DPDT topology, 40GHz frequency limit, and failsafe control characteristics. Interface compatibility and control voltage specifications must match exactly.
