R573402485

Overview

The R573402485 is a SP4T coaxial switch from the Ramses series by Radiall. It operates up to 18 GHz with SMA connectors and features a normally open configuration. The device utilizes a 12Vdc BCD TTL control interface via a D-sub connector. It includes built-in support for BCD decoding and supply diodes, designed for high-performance RF signal routing in demanding environments.

Feature Summary

• SP4T switching topology for multi-path signal routing
• Normally open contact configuration for default isolation
• Integrated BCD decoder and supply diode circuitry
• SMA interface compatible with standard RF infrastructure

Applications

• High-frequency test and measurement instrumentation
• Telecommunications base station signal distribution
• Aerospace and defense electronic warfare systems
• Automated RF testing equipment setups

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as lead times may vary. Confirm that the specific ordering suffix matches the required control interface and connector type. Ensure compliance with RoHS standards if applicable to your project requirements before finalizing procurement orders.

Selection Notes

Select this component when a four-port RF switching solution is required at frequencies up to 18 GHz. The integrated BCD control simplifies driver design compared to discrete logic solutions. Verify that the SMA connector style aligns with existing system cabling and that the 12Vdc control voltage is compatible with the host controller output levels.

Part Context

This part belongs to the Ramses family of microwave components, which are engineered for robust performance in harsh conditions. The series offers various configurations tailored for radar, communication, and sensing applications. The R573402485 specifically addresses needs for reliable, high-isolation switching in compact form factors using standard SMA interfaces.

Replacement Considerations

Consult official Radiall documentation for verified substitute part numbers within the Ramses series. Cross-reference pinouts and control logic compatibility carefully. Do not assume interchangeability with other manufacturers' SP4T switches without validating electrical parameters and mechanical dimensions against the original datasheet.
