R573403205

Overview

The R573403205 is a general purpose SP12T coaxial RF switch from the Ramses series by Radiall USA, Inc. It operates with a 50 Ohm impedance and supports frequencies up to 12.4 GHz. The device utilizes a normally open configuration activated by a 28Vdc coil voltage. Connectivity is provided via an SMA interface and a D-sub connector for control signals.

Feature Summary

• SP12T single-pole twelve-throw switching topology
• Ramses series design for high-frequency applications
• Normally open latching mechanism
• Integrated D-sub control interface

Applications

• RF signal routing in test and measurement equipment
• Telecommunications base station architectures
• Electronic warfare systems requiring multi-path signal selection
• Aerospace radar subsystems

Procurement Notes

Verify current manufacturing status directly with Radiall USA, Inc., as availability may vary. Confirm that the specific Ramses series variant matches your system's frequency and voltage requirements. Ensure compatibility with existing SMA connectors and D-sub control wiring before finalizing procurement decisions.

Selection Notes

Select this component when a high-port-count SP12T configuration is required within the 12.4 GHz range. The 28Vdc actuation voltage must align with available control power supplies. Verify that the D-sub connector footprint fits the enclosure design constraints alongside the SMA output ports.

Part Context

This part belongs to the Ramses family of coaxial switches, designed for robust performance in demanding RF environments. The series offers various throw counts and connector types, with the R573403205 specifically providing twelve output paths for complex signal distribution tasks.

Replacement Considerations

Direct substitutes include other Ramses series models with similar port counts or different connector interfaces such as R573403315. Cross-reference technical specifications carefully to ensure impedance and frequency limits remain compatible with the original design intent.
