R570453000

Overview

The R570453000 is a single-pole double-throw (SPDT) coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features SMA connectors and operates up to 18 GHz with a 50 Ohm impedance. The device utilizes latching technology for state retention and includes self-cut-off indicators. It requires a 28 Vdc supply voltage and employs diodes for pin terminals. The unit is designed for robust RF signal routing in high-frequency applications.

Feature Summary

• SPDT configuration with SMA interface
• Latching mechanism with self-cut-off indicators
• Operates at frequencies up to 18 GHz

Applications

• RF signal routing in test and measurement equipment
• Telecommunications infrastructure switching
• Aerospace and defense radar systems

Procurement Notes

Verify part authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required SMA connector and latching variant. Request official datasheets and material compliance certificates prior to purchase to ensure technical suitability for the intended application environment.

Selection Notes

Select this component when SPDT switching functionality is required within the 18 GHz frequency range. The latching feature ensures state stability without continuous power consumption for position holding. Ensure the system design accommodates the 28 Vdc operating voltage and provides adequate thermal management for the specified operating temperature range.

Part Context

This model belongs to the Ramses series of coaxial switches, which are engineered for high-reliability RF applications. The series offers various configurations including different port counts and connector types. The R570453000 specifically addresses needs for compact, high-frequency switching with mechanical latching capabilities in demanding environments.

Replacement Considerations

Consult Radiall documentation for verified substitute part numbers within the Ramses series. Cross-reference specifications such as frequency limits, connector type, and latching mechanisms to ensure functional equivalence. Do not assume compatibility with generic SPDT switches due to specific Ramses design parameters.
