R573403425LP

Overview

The R573403425LP is a general-purpose SP4T coaxial RF switch from the Ramses series, manufactured by Radiall USA, Inc. It operates within a frequency range of DC to 18 GHz and features a 50 Ohm impedance. The device utilizes a normally open configuration with a positive common terminal, actuated by a 28Vdc supply. It incorporates TTL diodes for control logic and connects via a D-sub connector interface.

Feature Summary

• SP4T single-pole four-throw switching topology
• Low PIM design characteristics
• SMA connector interface
• D-sub connector control interface

Applications

• Test and measurement instrumentation
• Telecommunications base stations
• Electronic warfare systems
• Radar signal routing

Procurement Notes

Verify the specific datasheet version and lot code requirements before procurement. Confirm that the D-sub connector mating specifications align with existing system harnesses. Ensure environmental conditions match the operational ratings defined in the official Radiall documentation for the Ramses series.

Selection Notes

Select this component when an SP4T configuration is required up to 18 GHz. The low PIM attribute makes it suitable for sensitive applications. Verify the 28Vdc control voltage compatibility. The SMA interface and D-sub control connection define the physical integration constraints.

Part Context

This part belongs to the Ramses family of coaxial switches. The series offers various configurations including SP3T, SP4T, and SP5T options. These components are designed for high-performance RF applications requiring reliable switching between multiple signal paths.

Replacement Considerations

Cross-reference with other Ramses series variants such as R573403315 or R573403510 if different port counts or connector types are needed. Verify mechanical footprint and control logic compatibility before substituting.
