R573403400LP

Overview

The Radiall R573403400LP is a SP6T coaxial switch from the Ramses series, designed for low passive intermodulation (PIM) applications. It operates up to 18 GHz with a 50 Ohm impedance and SMA connector interface. The device utilizes a normally open configuration driven by 28 VDC coil voltage. Key electrical specifications include a maximum VSWR of 1.5, insertion loss of 0.5 dB, and isolation of 60 dB. It features solder pin terminals and is supplied in bulk packaging.

Feature Summary

• Low PIM design optimized for high-fidelity RF signal integrity
• SP6T switching topology providing six distinct output positions
• SMA connector interface supporting frequencies up to 18 GHz

Applications

• Wireless infrastructure base stations requiring low distortion
• Test and measurement equipment demanding high isolation
• Military and aerospace radar systems
• Satellite communication ground stations

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm specific lot traceability and RoHS/REACH compliance documentation prior to acquisition. Ensure storage conditions align with manufacturer guidelines to maintain performance characteristics. Request detailed datasheets for final integration validation.

Selection Notes

Select this model when SP6T functionality is required alongside strict low PIM constraints. Compare against standard Ramses variants if higher power handling or different connector types are needed. Verify that the 28 VDC drive requirement matches available control circuitry. Assess thermal management needs based on expected duty cycles and ambient operating temperatures.

Part Context

This component belongs to the Ramses family of coaxial switches, known for robust performance in demanding RF environments. The 'LP' suffix denotes Low PIM capabilities, distinguishing it from standard versions. It serves as a critical switching element in complex RF signal routing architectures where signal purity is paramount.

Replacement Considerations

Direct substitutes within the Ramses series may include models with identical SP6T configurations but differing connector types or PIM ratings. Cross-reference part numbers such as R573403400 for standard PIM alternatives. Ensure mechanical footprint and terminal compatibility match existing PCB layouts before substitution.
