R574F92885

RF Switches Overview

The R574F92885 is a general-purpose RF switch IC manufactured by Radiall USA, Inc. It features an SP8T circuit configuration with a maximum test frequency of 26.5GHz and a 50-ohm impedance. The device utilizes the RAMSES series technology and includes SMA connectors for interfacing. It operates on a 12Vdc supply voltage and supports BCD TTL diode control logic. Key functional attributes include latching capability, self-cut-off behavior, and auto-reset functionality. Status indicators are integrated into the design.

RF Switches Feature Summary

• SP8T single-pole eight-throw switching architecture
• Integrated status indicators for operational visibility
• Latching mechanism with self-cut-off and auto-reset capabilities
• SMA connector interface for signal routing

RF Switches Applications

• RF signal distribution systems requiring high port counts
• Test and measurement equipment operating up to 26.5GHz
• Telecommunications infrastructure utilizing BCD TTL control interfaces

RF Switches Procurement Notes

Verify the specific datasheet version and electrical tolerances directly with Radiall USA, Inc. before integration. Confirm that the 12Vdc supply requirement aligns with system power constraints. Ensure SMA connector compatibility with existing PCB layouts. Check for any recent revisions to the RAMSES series specifications that may affect pinout or control logic timing.

RF Switches Selection Notes

Select this component when an SP8T configuration is required within the 26.5GHz frequency range. The 50-ohm impedance matches standard RF transmission lines. The BCD TTL interface simplifies digital control compared to analog drivers. Consider the physical size of the SMA connectors and the need for indicator lights in the final assembly design.

RF Switches Part Context

This part belongs to the RAMSES series of coaxial switches from Radiall. The series focuses on high-frequency performance with integrated control logic. The R574F92885 specifically addresses applications needing multiple output paths controlled via digital signals. It complements other SPnT variants in the lineup offering different throw counts.

RF Switches Replacement Considerations

R574G12325 offers similar RAMSES technology but provides an SP3T configuration instead of SP8T. Verify if the reduced port count meets system requirements. Both parts share the same general purpose RF switch classification and SMA interface style.
