Procurement Notes

Verify the specific ordering suffix and package variant against the official Radiall datasheet to ensure compatibility with your PCB footprint and thermal requirements. Confirm that the supply voltage specifications align with your system's power management design before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-pole six-throw switching solution is required for frequencies up to 18 GHz. Ensure the application can accommodate the 24V to 30V control voltage range. Consider the 50 Ohm impedance match for system integration. Evaluate the thermal performance and isolation requirements against the specified 60 dB minimum isolation and 0.5 dB maximum insertion loss metrics.

Part Context

This RF switch belongs to the RAMSES family from Radiall, which specializes in high-performance microwave and millimeter-wave components. The R573493685 specifically addresses the need for compact, low-loss switching in dense electronic assemblies. It complements other passive and active RF components in modern wireless and radar architectures.

Replacement Considerations

Check for direct substitutes within the same RAMSES series or compatible SP6T switches from Radiall. Verify pinout compatibility and electrical parameter equivalence, particularly regarding isolation and insertion loss at 18 GHz. Consult the manufacturer's obsolescence notices for any lifecycle changes.
