Overview
The R574393405 is a terminated coaxial switch manufactured by Radiall USA, Inc. It belongs to the Ramses series and features an SMA interface. The device operates as a Single-Pole Four-Throw (SP4T) configuration with a maximum frequency of 3 GHz. It utilizes latching indicators powered by 28Vdc diodes and includes a D-sub connector for control. The component is designed for reliable RF signal routing in demanding environments.
Feature Summary
- Terminated Ramses series coaxial switch design
- SP4T switching configuration with SMA interface
- Integrated latching indicators and 28Vdc diode control
- D-sub connector for external control integration
Applications
- RF signal routing in communication systems
- Test and measurement equipment requiring multi-path switching
- Aerospace and defense electronic subsystems
- Industrial automation control panels
Procurement Notes
Verify the specific manufacturing lot and date code upon receipt to ensure compliance with project timelines. Confirm that the D-sub connector orientation and pinout match the system integration requirements. Check for any physical damage to the SMA connectors during transit. Ensure storage conditions remain within specified limits to preserve component integrity before installation.
Selection Notes
Select this model when a compact SP4T switching solution with integrated status indication is required. The terminated design simplifies PCB layout by eliminating the need for external termination components. Consider the 3 GHz frequency limit and SMA interface compatibility with existing cabling infrastructure. Evaluate the 28Vdc control voltage against available power supplies in the target application environment.
Part Context
This component is part of Radiall's Ramses family of coaxial switches, known for high performance in RF applications. The R574393405 specifically addresses needs for multi-port signal management in space-constrained designs. Its terminated nature distinguishes it from non-terminated variants, offering immediate impedance matching without additional circuitry.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing control logic if considering alternative SP4T switches from other manufacturers.
