RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and power rating requirements against the official datasheet before ordering. Confirm that the SMA female interface matches the system design. Ensure the operating environment stays within the specified -30°C to +65°C limits. Check RoHS3 compliance status if required by project regulations. Validate the 25 W power handling capacity for the intended application load.

RF Circulators And Isolators Selection Notes

Select this model when a single-junction isolator is required for the 7.7–8.4 GHz band. Consider the 25 W power limit and 23 dB isolation performance for system matching. Evaluate the SMA female connector compatibility with existing circuitry. Compare insertion loss and VSWR values against system budget constraints. Verify thermal management capabilities within the specified operating temperature range.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D3I7784 series of RF isolators. It shares the same frequency range as other variants in the family but differs in power handling and isolation specifications. The series includes models with varying connector types and junction configurations. This specific part number denotes the standard SMA female version with defined electrical parameters.

RF Circulators And Isolators Replacement Considerations

D3I7784-2 is a variant within the same series offering different connector options. D4I7784-1 provides higher isolation at 46 dB but lower power handling at 10 W. Verify electrical parameter compatibility before substituting any alternative part numbers.
