R570443010

Overview

The R570443010 is an SPDT coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates up to 18 GHz with SMA connectors and features a latching mechanism powered by 28 Vdc. The device utilizes positive common topology with diode protection and pin terminals for secure integration.

Feature Summary

• SPDT configuration within the Ramses series
• Latching control mechanism with indicator functionality
• Positive common electrical topology

Applications

• RF signal routing in communication systems
• Test and measurement instrumentation
• Base station antenna switching

Procurement Notes

Verify current availability directly with Radiall or authorized distributors, as supply status may vary. Confirm that the 28 Vdc latching requirement aligns with system power specifications. Ensure SMA connector compatibility and pin terminal interface match the target PCB design before finalizing procurement orders.

Selection Notes

Select this component when high-frequency operation up to 18 GHz is required alongside a latching state retention feature. The positive common topology suits applications needing a defined default path. Verify that the 28 Vdc drive voltage is compatible with existing control circuitry and that SMA interfaces meet system impedance requirements.

Part Context

This part belongs to the Ramses family of coaxial switches, designed for robust RF performance. The Ramses series typically offers low insertion loss and high isolation across wide bandwidths. The R570443010 specifically integrates latching capabilities, distinguishing it from failsafe variants within the same product line.

Replacement Considerations

Consider the R570412030LP for similar frequency and connector types if a failsafe (non-latching) operation mode is acceptable instead of latching. Verify that the change in control logic and power consumption aligns with system design constraints before substitution.
