RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and junction type against project requirements before ordering. Confirm RoHS compliance status and environmental testing data if used in space-qualified hardware. Check current availability as this item may be subject to manufacturer lead times rather than immediate stock. Ensure mating connectors match the Type-K female specification to prevent interface mismatch.

RF Circulators And Isolators Selection Notes

Select this model when a 10 W power handling capacity and 36 dB isolation are required in the 18-26.5 GHz band. Consider the physical dimensions and mounting style relative to the system layout. Compare against other DiTom series parts like D4I1826 or D3I1826 variants if different connector genders or power levels are needed. Validate thermal management capabilities for the intended operating environment.
