R574392500

Overview

The R574392500 is a terminated coaxial switch manufactured by Radiall USA, Inc., belonging to the Ramses series. It features an SMA interface and operates as a Single-Pole Five-Throw (SP5T) configuration with a maximum frequency of 3 GHz. The device utilizes latching technology for state retention and requires a 28Vdc supply voltage for actuation. It incorporates pin terminals for circuit integration and includes self-centering auto-reset functionality to ensure reliable connection alignment during mating cycles.

Feature Summary

• SP5T switching topology with terminated output ports
• Ramses series design optimized for RF applications up to 3 GHz
• Latching mechanism maintains position without continuous power
• Self-centering auto-reset feature ensures precise connector alignment

Applications

• RF signal routing in communication systems
• Test and measurement equipment signal paths
• Wireless infrastructure component switching
• Aerospace and defense electronic subsystems

Procurement Notes

Verify the specific terminal type and electrical requirements against system schematics before procurement. Confirm that the 28Vdc latching voltage aligns with available control power supplies. Ensure the SMA interface compatibility matches connected cables and fixtures. Check current availability status as distribution channels may vary. Validate RoHS compliance if required by project specifications.

Selection Notes

Select this component when a five-port RF switching solution is required within the 3 GHz bandwidth. Consider the latching requirement for power-efficient operation where state retention is necessary. Evaluate the physical footprint and pin terminal style for PCB layout constraints. Compare performance metrics such as insertion loss and isolation against alternative SP5T switches if critical signal integrity is paramount.
