R573802410

Overview

The R573802410 is an SP4T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features SMA2.9 connectors and operates up to 40 GHz with a 50 Ohm impedance. The device utilizes a normally open configuration and requires a 12 Vdc supply voltage (10.2V ~ 13V). Key electrical specifications include a minimum isolation of 50 dB and a maximum insertion loss of 1.1 dB. It functions within an operating temperature range of -40°C to 85°C and is supplied in bulk packaging.

Feature Summary

• SP4T switching topology for signal routing
• High-frequency operation up to 40 GHz
• Normally open contact configuration
• SMA2.9 connector interface

Applications

• RF test and measurement equipment
• Wireless communication systems
• Aerospace and defense radar applications
• Satellite ground station infrastructure

Procurement Notes

Verify the specific datasheet version and mechanical drawings prior to integration. Confirm that the SMA2.9 connector mating requirements align with system cabling. Ensure power supply stability within the 10.2V to 13V range for reliable actuation. Check for any recent component lifecycle updates or obsolescence notices directly from Radiall USA, Inc. before finalizing procurement plans.

Selection Notes

Select this component when high-frequency signal routing up to 40 GHz is required. The SP4T configuration allows one common port to connect to four distinct output paths. Consider the normally open state for default signal path management. Verify compatibility with SMA2.9 connector standards and ensure thermal management supports the -40°C to 85°C operating range.
