R573003820

Overview

The R573003820 is a high-frequency RF relay manufactured by Radiall USA, Inc., belonging to the Ramses series. It features an SP8T (Single Pole Eight Throw) configuration with a positive common terminal design. The component operates at frequencies up to 3 GHz and utilizes a D-sub connector for control interface connections. It is designed as a normally open switch requiring a 12Vdc supply voltage for actuation. The unit is packaged in bulk format.

Feature Summary

• SP8T switching topology with positive common architecture
• Operational frequency range extending to 3 GHz
• Control via D-sub connector interface
• Normally open contact configuration

Applications

• RF signal routing in communication systems
• Test and measurement equipment switching matrices
• High-frequency circuit protection and isolation
• Automated test system configurations

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as stock levels fluctuate. Confirm that the specific ordering suffix matches the required control voltage and connector type. Ensure compliance with relevant environmental regulations such as RoHS standards before finalizing procurement orders for production integration.

Selection Notes

Select this component when an eight-channel RF switching solution is required within the 3 GHz bandwidth. The choice depends on the necessity for a positive common terminal arrangement and compatibility with D-sub control interfaces. Evaluate the mechanical fit for bulk packaging and ensure the 12Vdc drive requirement aligns with the system's power distribution capabilities.

Part Context

This part belongs to the Ramses family of high-frequency relays from Radiall, specialized for RF applications. The series offers various throw counts and control options, with the R573003820 specifically providing an eight-throw configuration.
