R573003425

Overview

The R573003425 is a Ramses series SP4T coaxial switch manufactured by Radiall. It features an N-type interface and operates up to 3 GHz. The device utilizes TTL control signals with diodes for actuation. It is designed as a normally open switch requiring 28Vdc power. The component uses positive common logic and connects via D-sub terminals.

Feature Summary

• SP4T switching configuration within the Ramses series
• N-type connector interface supporting frequencies up to 3 GHz
• TTL control logic with integrated diodes for actuation
• Normally open state with 28Vdc positive common operation

Applications

• RF signal routing in communication systems
• Test and measurement equipment setups
• Aerospace and defense electronic assemblies

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply chain conditions may vary. Confirm RoHS compliance details and specific packaging requirements before finalizing procurement orders. Ensure that the TTL control voltage levels match system specifications to guarantee proper switch actuation and long-term reliability.

Selection Notes

Select this component when a high-frequency SP4T coaxial switch is required for systems operating at 3 GHz. Ensure the design supports 28Vdc TTL control signals and accommodates the D-sub terminal interface. Verify that the normally open configuration aligns with the intended RF path management strategy and environmental constraints of the application.

Part Context

This part belongs to the Ramses family of coaxial switches from Radiall. The series is characterized by robust construction suitable for demanding environments. The R573003425 specifically integrates N-type connectors and TTL control, distinguishing it from other variants that may use different interfaces or drive voltages within the same product line.

Replacement Considerations

Consult official Radiall documentation for verified substitute part numbers. Cross-reference interface types, control logic, and frequency ranges to ensure functional compatibility. Do not assume interchangeability with similar models without verifying specific electrical and mechanical parameters.
