R570442010

Overview

The R570442010 is a SPDT coaxial switch from the Ramses series by Radiall, designed for high-frequency applications up to 18 GHz. It features an SMA connector interface and operates with a 12 VDC coil voltage. The device utilizes latching technology with positive common configuration and includes status indicators. Electrical specifications include a maximum VSWR of 1.4:1, insertion loss of 0.35 dB, and isolation of 60 dB. It supports 50 Ohm impedance and offers a mechanical life of 10 million cycles within a temperature range of -40°C to +85°C.

Feature Summary

• Latching mechanism with positive common configuration for stable state retention without continuous power.
• Integrated status indicators provide visual feedback on the current switching position.
• High-frequency performance capability up to 18 GHz with low insertion loss.
• Robust construction supporting 10 million operational cycles.

Applications

• RF test and measurement equipment requiring reliable signal routing
• Telecommunications infrastructure systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain integrity of the SMA connectors. Validate electrical parameters against specific application requirements using the latest published specification documents.

Selection Notes

Select this model when latching functionality is required to reduce power consumption during static states. The 12 VDC drive voltage suits systems with lower control voltage availability compared to 28 VDC variants. Verify that the SMA interface matches existing board layouts. Consider the 18 GHz frequency limit for signal integrity in high-speed designs.

Part Context

This component belongs to the Ramses family of coaxial switches, engineered for demanding RF environments. The series emphasizes reliability and precise signal handling across microwave frequencies. The R570442010 variant specifically addresses applications needing latching behavior and integrated status indication within a compact form factor.

Replacement Considerations

Consult official substitution lists for electrically compatible alternatives. Verify pinout compatibility and voltage requirements before swapping. Ensure frequency range and connector type match the original design constraints.
