RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration requirements against the official datasheet, as port arrangements may vary. Confirm RoHS compliance status and environmental ratings prior to integration. Ensure that the thermal management strategy accommodates the specified operating temperature range of -20°C to +65°C. Cross-reference the mechanical dimensions with the host assembly to guarantee proper fitment within the designated module space.

RF Circulators And Isolators Selection Notes

Select this component when a four-port circulator is required for the 18-26.5 GHz band. Consider the dual junction architecture if higher isolation or specific phase characteristics are needed compared to single-junction alternatives. Evaluate the Type-K connector interface compatibility with existing system cabling. Assess the 10 W average power handling capability against the maximum expected signal levels in the application circuit.

RF Circulators And Isolators Part Context

This part belongs to the D4C1826 series of RF circulators from DiTom Microwave. It shares the same frequency range and core electrical specifications with variants such as the D4C1826K-1 and D4C1826K-4, which differ primarily in connector configurations. The series is designed for high-performance microwave applications requiring reliable signal directionality and low insertion loss within the K-band spectrum.
