RF Circulators And Isolators Procurement Notes

Verify the specific ordering suffix (e.g., -3) against the required connector type and pin configuration. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies. Ensure the selected variant matches the system's impedance and power handling requirements before finalizing procurement orders.

RF Circulators And Isolators Selection Notes

Select this model when a wideband isolator covering 950 MHz to 2.15 GHz is required. Evaluate the 75 W power rating against peak system loads. Consider the SMA connector compatibility with existing PCB or cable assemblies. Verify that the 12 dB isolation meets the noise floor requirements of the downstream receiver chain.

RF Circulators And Isolators Part Context

This component belongs to the D3I9521 series of RF isolators from DiTom Microwave. It is categorized under RF Circulators and Isolators within the broader RF and Wireless product family.
