RF Switches Procurement Notes

Verify the specific datasheet version corresponding to the ordered quantity to ensure compliance with current RoHS status and lead time requirements. Confirm that the 28Vdc operating voltage aligns with the host system's power supply capabilities. Ensure SMA connector mating compatibility with existing PCB layouts or cable assemblies prior to final procurement authorization.

RF Switches Selection Notes

Select this component when a compact SP4T switching solution is required for frequencies up to 6GHz. The low insertion loss of 0.3dB makes it suitable for sensitive signal paths. Consider the positive common logic requirement for control circuitry design. The subminiature form factor is ideal for space-constrained enclosures where standard SMA modules do not fit.

RF Switches Part Context

This part belongs to Radiall's series of subminiature coaxial switches. It is designed for high-reliability applications requiring fast switching speeds and stable performance across a broad frequency spectrum. The module integrates diode technology to achieve the specified isolation and insertion loss characteristics within a small footprint.

RF Switches Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify mechanical dimensions and pinout configurations if considering alternative manufacturers. Ensure replacement components meet the same 50 Ohm impedance and 6GHz frequency range specifications.
