Overview
The R573412425 is an SP4T coaxial switch from the Ramses series by Radiall USA, Inc. It features SMA connectors and operates up to 18 GHz. The device uses a normally open topology with TTL diodes and D-sub connector control. It supports 12Vdc or 28Vdc input voltages and includes indicator functionality. The unit is designed for free-hanging installation and utilizes PTFE dielectric material.
Feature Summary
- SP4T circuit topology for signal routing
- SMA interface connectors
- TTL diode control logic
- Integrated status indicators
Applications
- RF signal switching systems
- Test and measurement equipment
- Telecommunications infrastructure
- Aerospace electronic assemblies
Procurement Notes
Verify the specific voltage requirement (12Vdc vs 28Vdc) against the datasheet revision, as sources indicate variations. Confirm the presence of indicators if required. Check RoHS compliance details directly with the manufacturer. Ensure the D-sub connector type matches the system interface. Validate the operating temperature range for the intended environment.
Selection Notes
Select this component when an SP4T configuration is required within the Ramses series. Consider the 18 GHz frequency limit for high-speed applications. Evaluate the need for integrated indicators versus external monitoring. Assess the compatibility of the TTL diode control signals with the host system. Compare thermal performance against the -40°C to 85°C specification.
Part Context
This part belongs to the Ramses family of coaxial switches. It shares design principles with other models in the series but differs in port count and frequency range. The SP4T variant provides four output paths controlled by a single input. It complements lower-frequency or different-port-count options available from Radiall.
Replacement Considerations
R573403225 offers similar Ramses architecture but operates at 12.4 GHz with SP12T topology. R573413425 provides SP4T configuration but requires 28Vdc input instead of 12Vdc. Verify electrical parameters and control voltage compatibility before substitution.
