RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration required for the application, as the D4I3783 series includes variants such as D4I3783-3 with male-to-male interfaces. Confirm availability status directly with authorized distributors, as supply levels may vary. Ensure compliance with RoHS3 standards and check export classification codes like EAR99 for regulatory requirements before finalizing procurement orders.

RF Circulators And Isolators Selection Notes

Select this component when a broadband isolator covering 3.7 to 8.3 GHz is needed for S-band applications. Consider the 20 W power rating and physical dimensions of 2x0.5x1 inches for integration into existing RF chains. Verify that the SMA connector type matches the system interface requirements and that the operating temperature range of 0 to +50°C suits the environmental conditions.

RF Circulators And Isolators Part Context

The D4I3783 belongs to the DiTom Microwave D4I3783 series of single and dual junction RF isolators. This family includes related part numbers such as D4I3783-2 and D4I3783-3, which share similar frequency and power specifications but may differ in connector configurations or packaging details. The series is categorized under RF circulators and isolators for wireless applications.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include D4I3783-2 and D4I3783-3. Verify connector polarity and mechanical footprint compatibility before substitution. Cross-reference datasheets to ensure identical electrical performance parameters, particularly regarding isolation and VSWR values.
