R573102800

Overview

The R573102800 is an SP8T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features a Type N connector interface and operates at frequencies up to 8 GHz with a 50 Ohm impedance. The device utilizes a normally open configuration controlled by a 12Vdc TTL signal. Key electrical specifications include a maximum insertion loss of 0.5 dB and a minimum isolation of 70 dB at the test frequency of 8 GHz. The supply voltage range is specified between 10.2V and 13V.

Feature Summary

• Eight-channel single-pole switching capability within the Ramses series architecture
• High-frequency operation supporting signals up to 8 GHz
• Normally open state design for default signal path management
• TTL-compatible control interface for straightforward integration

Applications

• RF signal routing in communication systems
• Test and measurement equipment configurations
• Phased array antenna feed networks
• Automated testing setups requiring multi-path selection

Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct factory channels. Confirm current production status and lead times directly with the manufacturer as availability may vary. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this model when eight distinct RF paths require switching within an 8 GHz bandwidth. The Type N interface suits applications needing robust mechanical connections. Verify that the 12Vdc control logic matches the system's available drive levels and that the 50 Ohm impedance aligns with the surrounding circuitry design constraints.

Part Context

This component belongs to the Ramses family of high-performance coaxial switches designed for demanding RF environments. The series offers various pole counts and connector options, with the R573102800 specifically providing eight-way switching functionality. It represents a solution for complex signal distribution tasks requiring reliable high-frequency performance.

Replacement Considerations

Consider the R573102805 if a D-sub connector interface is preferred over pins and terminals while maintaining similar electrical characteristics. Verify pinout compatibility and mechanical mounting differences before substituting to ensure seamless integration into existing hardware layouts.
