R573412305

Overview

The R573412305 is a SP3T coaxial switch from the Ramses series by Radiall, operating up to 18 GHz with a 50 Ohm impedance. It features SMA connectors and a D-sub connector interface for control. The device operates on 12 VDC coil voltage with normally open contacts. Key electrical parameters include a VSWR of 1.5:1, insertion loss of 0.5 dB, and isolation of 60 dB. It supports a mechanical life of 5,000,000 cycles within a temperature range of -40°C to +85°C.

Feature Summary

• SP3T configuration with SMA connectors for high-frequency signal routing
• 12 VDC coil voltage operation with D-sub connector control interface
• Normally open contact design ensuring default open state
• Integrated status indicators for operational monitoring

Applications

• RF test and measurement equipment requiring high-isolation switching
• Telecommunications infrastructure signal distribution systems
• Aerospace and defense radar system signal routing
• Electronic warfare simulation and testing environments

Procurement Notes

Verify current availability and lifecycle status directly with Radiall or authorized distributors, as supply chain conditions may vary. Confirm that the D-sub connector interface and 12Vdc control requirements align with existing system designs. Ensure environmental specifications meet operational temperature ranges. Request updated datasheets for precise electrical tolerances before integration.

Selection Notes

Select this model when an 18 GHz frequency range and SP3T topology are required. The 12 VDC coil voltage and D-sub connector interface dictate specific power and control circuitry needs. Compare VSWR and isolation metrics against other Ramses variants if stricter performance thresholds are necessary. Verify mechanical life expectations against application duty cycles.
