Procurement Notes

Verify component authenticity directly with Radiall USA, Inc. or authorized distributors before purchase. Confirm current manufacturing status and lead times as availability may vary. Ensure compliance with RoHS directives and specific environmental requirements for your application. Request official datasheets to validate technical parameters against system specifications prior to integration.

Selection Notes

Select this model when SP6T topology is required for signals extending to 40 GHz. The 12Vdc TTL control interface suits standard digital logic levels. Consider the D-sub connector type for cabling compatibility. Evaluate the 50 Ohm impedance match against system requirements. Assess the mechanical cycle rating against expected operational duty cycles in the target environment.

Part Context

This component belongs to the Ramses family of coaxial switches designed for high-performance RF applications. The series offers various configurations including SP3T and SPDT variants with different frequency ranges and control voltages. The R573812625 specifically targets high-frequency needs with its 40 GHz limit and SMA2.9 interface, distinguishing it from lower-frequency models in the same product line.

Replacement Considerations

Consult official documentation for direct substitutes. Verify pinout compatibility and control voltage requirements when considering alternatives. Ensure replacement components meet or exceed the 40 GHz frequency specification and maintain similar isolation and insertion loss characteristics for seamless system integration.
