R573493485

Overview

The R573493485 is an SP4T RF switch from the RAMSES series by Radiall USA, Inc. It utilizes SMA connectors and operates up to a maximum frequency of 18 GHz. The device features a latching mechanism for state retention. It is designed for surface-mount integration into RF and IF circuits requiring high-frequency signal routing with low insertion loss and high isolation characteristics typical of solid-state microwave switches.

Feature Summary

• Single Pole Four Throw (SP4T) switching architecture
• SMA connector interface for reliable mating
• Latching functionality maintains state without continuous power
• Surface-mount package design for automated assembly

Applications

• RF front-end modules in communication systems
• Test and measurement instrumentation signal routing
• Wireless infrastructure base station components
• Satellite communication payload switching networks

Procurement Notes

Verify the specific datasheet version for precise pinout configurations and thermal management requirements. Confirm RoHS compliance status and lead time availability directly with authorized distributors. Ensure handling procedures meet ESD sensitivity standards during installation. Cross-reference mechanical drawings for PCB footprint accuracy before finalizing procurement orders.

Selection Notes

Select this component when an SP4T configuration with SMA interfaces is required at frequencies up to 18 GHz. The latching feature reduces power consumption compared to non-latching alternatives. Evaluate thermal dissipation capabilities within the target enclosure. Consider the surface-mount form factor for compatibility with existing SMT production lines and space-constrained designs.

Part Context

This part belongs to the RAMSES series of RF switches, which are engineered for high-performance microwave applications. The series offers various configurations tailored for different frequency ranges and connector types. The R573493485 specifically addresses needs for multi-path signal distribution in compact electronic assemblies requiring robust connectivity.

Replacement Considerations

Check for direct substitutes within the same RAMSES family or other Radiall RF switch lines offering compatible SMA interfaces and similar SP4T topologies. Verify that alternative parts match the 18 GHz frequency limit and latching mechanism requirements. Ensure mechanical dimensions and pin assignments align with the existing PCB layout to facilitate drop-in replacement.
