RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation when ordering, as the base model D3I1822 and variant D3I1822-1 share identical core electrical parameters but may differ in packaging or manufacturing revisions. Confirm RoHS3 compliance status and EAR99 export classification requirements prior to procurement. Ensure SMA female connector compatibility with system interconnects. Check current manufacturer lead times, as standard delivery periods are subject to change based on production schedules.

RF Circulators And Isolators Selection Notes

Select this component for applications requiring high isolation in the K-band spectrum. The 20 dB isolation rating ensures effective signal directionality. The 0.5 dB insertion loss minimizes signal attenuation. The 1.25 VSWR indicates good impedance matching. Consider the 10 W power limit for thermal management. Verify that the SMA female interface matches the host circuit board or cable assembly requirements.

RF Circulators And Isolators Part Context

The D3I1822-1 belongs to the DiTom Microwave D3I series of RF isolators. These components are engineered for microwave and millimeter-wave applications. The series typically utilizes ferrite materials to achieve non-reciprocal transmission characteristics. The D3I1822-1 variant specifically targets the 17.3–22.0 GHz range, offering a standardized module form factor for easy integration into larger microwave assemblies.
