R573102805

Overview

The R573102805 is a SP8T coaxial switch from the Ramses series by Radiall. It features an N-type connector interface and operates up to 8GHz. The device is normally open with a 12Vdc TTL control signal via D-sub connector. Key electrical parameters include a minimum isolation of 70dB, maximum insertion loss of 0.5dB at 8GHz, 50Ohm impedance, and a supply voltage range of 10.2V to 13V.

Feature Summary

• SP8T configuration for multi-path signal routing
• Normally open state for default signal path management
• D-sub connector interface for digital control input

Applications

• RF test and measurement instrumentation
• Telecommunications base station testing
• Aerospace and defense radar systems

Procurement Notes

Verify current availability status directly with Radiall or authorized distributors as stock levels fluctuate. Confirm lead times and specific packaging requirements prior to order placement. Ensure compatibility with existing D-sub control interfaces and 12Vdc power supplies in the target system design.

Selection Notes

Select this component when an eight-port switching solution is required within the 8GHz frequency range. The N-type interface suits applications needing robust mechanical connections. Verify that the 70dB isolation specification meets system noise floor requirements and that the 0.5dB insertion loss is acceptable for signal integrity.

Part Context

This part belongs to the Ramses family of coaxial switches designed for high-performance RF applications. The series offers various pole configurations and connector types. The R573102805 specifically addresses needs for eight-channel switching with standard N-type connectors and TTL logic control.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching SP8T topology, N-type interface, 8GHz limit, and D-sub control specifications.
