R573803420

Overview

The R573803420 is a single-pole four-throw (SP4T) radio frequency switch manufactured by Radiall USA, Inc. It belongs to the RAMSES series and utilizes SMA2.9 connectors. The device operates up to a maximum frequency of 40 GHz. It features a normally open configuration and is designed for surface-mount integration. The component requires a 28 Vdc control voltage with TTL logic levels for operation.

Feature Summary

• Single-pole four-throw switching architecture
• SMA2.9 connector interface
• Normally open state design
• TTL logic level control compatibility

Applications

• RF signal routing in high-frequency systems
• Test and measurement equipment
• Telecommunications infrastructure
• Aerospace and defense radar systems

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to procurement. Confirm that the 28 Vdc TTL control requirements align with the system's power supply and logic levels. Ensure the SMA2.9 connector mating compatibility with existing cable assemblies or PCB layouts. Check for any recent updates to the RoHS compliance status or environmental certifications.

Selection Notes

Select this component when a compact SP4T RF switch is required for frequencies up to 40 GHz. The choice is driven by the need for a normally open configuration and direct TTL control without additional driver circuitry. Consider the SMA2.9 interface standard for board space constraints and high-frequency performance needs compared to larger connector types.
