R577313105

RF Switches Overview

The R577313105 is a DPDT coaxial switch from the Ramses series by Radiall, designed for high-performance RF applications up to 3 GHz. It features a failsafe mechanism and operates with a 28 VDC coil voltage controlled via TTL diodes. The component utilizes SMA connectors and includes a D-sub connector with a bracket for interface connectivity. Key electrical specifications include a minimum isolation of 80 dB and a maximum insertion loss of 0.2 dB at 3 GHz, with a characteristic impedance of 50 Ohms.

RF Switches Feature Summary

• Failsafe operation ensures reliable switching states without continuous power maintenance
• High isolation performance minimizes signal leakage between ports
• Low insertion loss preserves signal integrity in RF paths
• Integrated D-sub connector simplifies control wiring and mounting

RF Switches Applications

• RF test and measurement equipment requiring precise signal routing
• Telecommunications base stations needing low-loss switching
• Aerospace and defense systems demanding high reliability
• Automotive radar testing environments

RF Switches Procurement Notes

Verify availability directly with Radiall or authorized distributors as stock status may vary. Confirm RoHS and REACH compliance requirements for your specific region. Ensure the ordering suffix matches the required connector type and control interface. Request official datasheets for detailed mechanical drawings and environmental ratings before finalizing procurement decisions.

RF Switches Selection Notes

Select this model when a DPDT configuration is required for frequencies up to 3 GHz. Consider the failsafe feature if system safety depends on default switch positions. Evaluate the 28 VDC TTL control interface compatibility with existing driver circuits. Compare insertion loss and isolation metrics against application thresholds to ensure signal quality standards are met.

RF Switches Part Context

This component belongs to the Ramses series of coaxial switches, which are engineered for robust performance in demanding RF environments. The series offers various configurations including SPDT and DPDT options with different connector types such as TNC and SMA. These switches are characterized by their compact design and high-frequency capabilities suitable for modern communication systems.

RF Switches Replacement Considerations

Direct substitutes within the Ramses series include models like R577033105 or R577123105, depending on frequency and connector requirements. Verify that replacement parts match the DPDT contact form, 28 VDC coil voltage, and TTL control logic. Ensure mechanical dimensions and D-sub connector compatibility remain consistent for seamless integration into existing assemblies.
