R574303885

Overview

The R574303885 is an SP8T terminated Ramses RF switch manufactured by Radiall USA, Inc. It operates with a maximum frequency of 3 GHz and utilizes SMA connectors. The device features latching functionality with self-clearing open state and auto-reset capabilities. Control inputs support BCD, TTL, and diode logic levels. It requires a 12Vdc or 28Vdc power supply depending on the specific configuration variant. The unit includes indicator lights for status monitoring and employs a D-sub connector for control interface termination.

Feature Summary

• SP8T switching topology with terminated Ramses architecture
• Latching mechanism with self-clearing open state and auto-reset function
• Integrated LED indicators for operational status monitoring
• D-sub connector interface for control signal termination

Applications

• RF signal routing in test and measurement equipment
• Telecommunications base station signal distribution
• Aerospace and defense radar system switching
• Automated test system multiplexing

Procurement Notes

Verify the exact control voltage requirement (12Vdc vs 28Vdc) and logic level compatibility (BCD, TTL, or Diode) against the specific datasheet revision. Confirm the presence of auto-reset functionality if required for the application design. Ensure the D-sub connector type matches the existing harness infrastructure to avoid adapter requirements during integration.

Selection Notes

Select this component when an eight-channel RF switching solution with latching memory and visual status feedback is required. The terminated Ramses design ensures stable impedance matching across the 3 GHz bandwidth. Consider the D-sub control interface for simplified wiring compared to discrete pin connections. Verify environmental ratings if operating in extreme temperature conditions beyond standard specifications.

Part Context

This part belongs to the Ramses series of high-performance RF switches designed for demanding applications. The series offers various pole configurations and control interfaces. The R574303885 specifically provides eight-way switching capability with integrated diagnostics. It represents a specialized solution for systems requiring reliable signal path management without external relay components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Ramses series models only if they match the SP8T configuration, SMA interface, and identical control voltage specifications. Verify mechanical footprint compatibility before considering alternative vendors.
