R574103300

Overview

The R574103300 is a single-pole triple-throw (SP3T) coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features N-type terminated connectors and operates at frequencies up to 12.4 GHz with a 50 Ohm impedance. The device utilizes normally open contacts and is driven by a 28 Vdc coil voltage via pin terminals. Key electrical specifications include a maximum insertion loss of 0.5 dB, a voltage standing wave ratio (VSWR) of 1.5:1, and isolation of 60 dB. It supports a mechanical life of 2,000,000 cycles and functions within a temperature range of -40°C to +85°C.

Feature Summary

• SP3T configuration with N-type terminated connectors for high-frequency signal routing
• Normally open contact design ensuring default non-conductive state when de-energized
• Robust mechanical endurance rated for two million operational cycles
• Integrated indicator functionality for visual status monitoring

Applications

• Test and measurement instrumentation requiring precise RF signal switching
• Telecommunications infrastructure for antenna or line selection
• Electronic warfare systems demanding high-isolation signal paths
• Aerospace and defense radar subsystems

Procurement Notes

Verify current availability directly with Radiall USA, Inc., as distribution channels may indicate limited stock or discontinuation status. Confirm RoHS compliance details and specific packaging requirements prior to ordering. Ensure that the 28 Vdc drive voltage matches existing control circuitry capabilities. Request updated lifecycle information to confirm long-term supply stability for production integration.

Selection Notes

Select this component when an SP3T topology with N-type interfaces is required for applications operating below 12.4 GHz. The 28 Vdc coil specification necessitates compatible driver electronics. Consider the 0.5 dB insertion loss and 60 dB isolation metrics against system signal integrity requirements. Verify that the physical dimensions and pin terminal mounting style fit the intended PCB or chassis layout constraints.

Part Context

This part belongs to the Ramses family of coaxial switches, designed for high-performance RF applications. The Ramses series typically offers various connector options and pole configurations. The R574103300 specifically addresses needs for N-type connectivity and 12.4 GHz bandwidth. It represents a standard electromechanical solution within Radiall's portfolio of precision switching components.

Replacement Considerations

Consult official Radiall documentation for direct cross-reference substitutes. Verify that any alternative maintains identical N-type termination, 28 Vdc coil voltage, and SP3T functionality. Ensure frequency limits and electrical parameters meet or exceed original specifications. Confirm mechanical compatibility for existing mounting arrangements.
