R573403285

Overview

The R573403285 is a general-purpose RF coaxial switch manufactured by Radiall USA, Inc. It belongs to the Ramses series and features an SP12T configuration with SMA connectors. The device operates at a maximum frequency of 12.4 GHz and maintains a 50 Ohm impedance. It utilizes a normally open switching mechanism controlled by a 28 Vdc supply. The unit employs BCD TTL diode logic for control inputs and connects via a D-sub connector interface.

Feature Summary

• SP12T single-pole twelve-throw coaxial switching architecture
• SMA female connector interface for signal paths
• Normally open contact configuration for default state safety
• BCD TTL diode logic control input via D-sub connector

Applications

• RF test and measurement instrumentation systems
• Telecommunications base station signal routing
• Aerospace and defense electronic warfare subsystems
• Automotive radar development and validation setups

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm datasheet revisions match specific production batches. Ensure environmental compliance documentation aligns with project requirements. Validate connector mating cycles and operational lifespan against application stress profiles before finalizing procurement orders.

Selection Notes

Select this model when high channel count (12 ports) is required within a compact form factor. The 12.4 GHz frequency rating suits most standard microwave applications. Verify that the 28 Vdc control voltage matches available system power rails. Ensure physical space accommodates the D-sub control interface alongside the SMA signal connections.

Part Context

This component is part of the Ramses family of coaxial switches designed for robust RF signal management. The series offers various throw configurations ranging from SP3T to SP12T. These switches are engineered for reliability in demanding environments, providing low insertion loss and high isolation characteristics typical of high-frequency electromechanical switching solutions.

Replacement Considerations

Consider the R573403205 as a potential alternative within the same Ramses series. Both models share the SP12T configuration and 12.4 GHz frequency limit. Verify control logic compatibility and mechanical footprint alignment before substituting components in existing designs.
