R570443030LP

Overview

The R570443030LP is an SPDT coaxial switch from the Ramses series, designed for low passive intermodulation (PIM) applications. It features SMA connectors and operates up to 18GHz. The device utilizes a latching mechanism with positive common configuration, powered by 28Vdc. Key electrical specifications include a maximum insertion loss of 0.35dB and minimum isolation of 60dB. It employs diode pins for terminals and is housed in a bulk package.

Feature Summary

• Low PIM design optimized for signal integrity
• Latching topology for stable state retention
• SMA interface supporting high-frequency operation

Applications

• Telecommunications infrastructure testing
• Aerospace and defense RF systems
• Medical equipment signal routing

Procurement Notes

Verify availability directly with Radiall USA, Inc., as distribution channels may vary. Confirm lead times and specific packaging requirements before ordering. Ensure compatibility with existing SMA connector interfaces and 28Vdc control logic. Check RoHS compliance status for regulatory adherence in target markets.

Selection Notes

Select this component when low PIM performance is critical for sensitive RF measurements. The 18GHz frequency range suits wideband applications. Consider the latching feature for power efficiency in static states. Verify that the SMA interface matches system requirements rather than N-type alternatives found in other Ramses variants.

Part Context

Part of the Ramses family of coaxial switches known for reliability in harsh environments. Designed for aerospace, defense, and telecom sectors. Differentiated by its low PIM characteristics and SMA connectivity, distinguishing it from higher-power or different connector type models within the broader Radiall portfolio.

Replacement Considerations

R570433030 is a comparable SPDT Ramses model but uses N-type connectors instead of SMA. Verify interface compatibility before substitution. Other Ramses variants may offer different frequency ranges or contact configurations.
