RF Circulators And Isolators Procurement Notes

Verify the specific suffix requirements against the official datasheet before ordering, as variations exist within the series. Confirm connector gender and mounting style matches the system design. Check current availability status, as supply chain constraints may affect lead times for this component type.

RF Circulators And Isolators Selection Notes

Select this model when a 4-8 GHz isolator with 20 dB isolation is required. Ensure the 30 W average power rating meets the system's forward power demands. Verify that the operating temperature range of -10°C to +60°C aligns with the environmental conditions of the application.

RF Circulators And Isolators Part Context

This part belongs to the D3I4080 series of RF isolators manufactured by DiTom Microwave. The series includes variants such as the D3I4080YMG-2, which is a cryogenic version rated for temperatures at or below 77K. While sharing similar electrical specifications, the D3I4080-3 is optimized for standard ambient temperature operations.
