R570612000

Overview

The R570612000 is a single-pole double-throw (SPDT) coaxial switch from the Ramses TNC series, manufactured by Radiall USA, Inc. It features a TNC connector interface and operates up to a maximum frequency of 12.4 GHz. The device utilizes a failsafe switching mechanism powered by a 12Vdc supply with pin terminals for connection. Constructed for high reliability, it supports continuous wave power handling typical of its class and maintains a 50 Ohm impedance. The unit is designed for robust performance across extreme temperatures ranging from -65°C to +165°C.

Feature Summary

• Failsafe SPDT switching architecture ensures defined state upon power loss
• TNC connector interface supporting frequencies up to 12.4 GHz
• 12Vdc coil drive with pin terminal configuration
• Extended operational temperature range for harsh environments

Applications

• RF signal routing in communication systems
• Test and measurement equipment
• Aerospace and defense electronics
• Automotive radar systems

Procurement Notes

Verify the specific datasheet version and mechanical drawings prior to integration. Confirm that the 12Vdc operating voltage aligns with system power rails. Ensure pin terminal compatibility with PCB or cable assembly designs. Check for RoHS compliance status if required by project specifications. Validate thermal management requirements given the wide operating temperature range.

Selection Notes

Select this component when a fail-safe RF path is critical for system safety or integrity. The TNC interface suits applications requiring secure threaded connections at frequencies below 12.4 GHz. Consider the 12Vdc drive requirement against available control voltages. Evaluate the physical size and pin layout against board space constraints compared to SMA or BNC alternatives.

Part Context

This part belongs to the Ramses family of coaxial switches, known for high reliability in demanding environments. The Ramses series offers various connector types and switching configurations. The R570612000 specifically addresses needs for TNC interfaces with failsafe functionality. It complements other Ramses models like R570012000 and R570813100 which offer different connector styles and frequency ranges.

Replacement Considerations

R570012000: Ramses N 3GHz Failsafe 12Vdc. Note the lower frequency limit and N-type connector. R570813100: Ramses SMA 40GHz Failsafe 28Vdc. Note the higher frequency, SMA connector, and different drive voltage. Verify mechanical fit and electrical specs before substitution.
