R573283405

Overview

The R573283405 is an SP4T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates with a maximum frequency of 3 GHz and maintains a 50 Ohm impedance. The device utilizes a latching actuator mechanism and features a self-cut-off function with auto-reset capability. It is powered by a 28V DC supply (range 24-30V) with negative common configuration. Electrical specifications include a nominal current of 250 mA. Physical connectivity is provided via a 25-pin D-sub male connector interface.

Feature Summary

SP4T switching topology for signal routing
Latching actuator mechanism for state retention
Self-cut-off functionality with auto-reset capability
Integrated 25-pin D-sub male connector interface

Applications

RF signal routing in test and measurement equipment
Telecommunications infrastructure switching
Aerospace and defense electronic systems
Automated test system configurations

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical dimensions. Ensure the power supply matches the 28V DC negative common requirement. Confirm that the 25-pin D-sub mating connector is compatible with the switch terminals. Check RoHS compliance status if required for the specific application environment.

Selection Notes

Select this component when a reliable SP4T switching solution is needed up to 3 GHz. The latching feature eliminates continuous power consumption for state holding. The integrated D-sub connector simplifies wiring compared to discrete relay assemblies. Consider the 250 mA nominal current limit when designing the load circuitry.

Part Context

This part belongs to the Ramses series of coaxial switches, designed for high-reliability applications. It integrates multiple RF paths into a single compact unit. The design emphasizes robust mechanical latching and precise electrical performance within the VHF/UHF range.

Replacement Considerations

No public confirmed substitute part numbers are available in the source data. Verify compatibility with existing PCB layouts and connector pinouts before considering alternative models.
