R574313515

Overview

The R574313515 is an obsolete RF switch IC from Radiall, part of the RAMSES series. It features a Single-Pole-5-Throw (SP5T) configuration with SMA connectors and is designed for normally open operation. The device utilizes Silicon technology and operates on a positive common D-sub connector interface. Key electrical parameters include a frequency range up to 3 GHz, a supply voltage of 28 VDC, and a rated current of 4 A. It functions within a temperature range of -40°C to 85°C.

Feature Summary

• Single-Pole-5-Throw (SP5T) RF switching architecture
• SMA terminated interface design
• Normally open operational mode
• Silicon-based integrated circuit construction

Applications

• RF signal routing in wireless communication systems
• Test and measurement equipment signal paths
• Industrial control system RF interfaces

Procurement Notes

This component is officially listed as Obsolete by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify authenticity and condition carefully when sourcing from third-party distributors. Ensure compatibility with existing SMA and D-sub connector requirements before procurement.

Selection Notes

Select this model only if SP5T topology at 3 GHz is required. Note that it uses a positive common D-sub connector rather than standard surface mount packages. Consider alternative active models if long-term supply stability is critical, as this specific part number is no longer in production.

Part Context

Part of the RAMSES family of RF switches. Manufactured by Radiall USA, Inc. Uses Silicon technology. Designed for high-frequency applications requiring reliable signal switching between multiple ports.

Replacement Considerations

No public confirmed substitute part numbers are available for this obsolete component. Users must evaluate functional equivalents based on SP5T topology, 3 GHz frequency limit, and SMA/D-sub interface compatibility.
