RF Circulators And Isolators Procurement Notes

Verify the specific ordering suffix and connector configuration against the official DiTom Microwave datasheet before purchase. Confirm that the SMA female interface matches your system requirements. Ensure the operating temperature range of -20°C to +65°C aligns with your environmental conditions. Check RoHS3 compliance status if required by your manufacturing standards. Validate the 150 W power rating against your peak operational loads.

RF Circulators And Isolators Selection Notes

Select this model when a 1.6–1.8 GHz frequency band is required with high isolation capabilities. Consider the 150 W power handling capacity for high-power transmitter applications. Evaluate the 0.8 dB insertion loss impact on overall system gain. Ensure compatibility with SMA female connectors used in the signal chain. Compare VSWR specifications against system reflection tolerance limits.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave RF isolator series, specifically engineered for microwave frequency applications. It serves as a passive two-port device allowing signal flow in one direction while blocking reverse reflections. The module format with integrated SMA connectors facilitates easy mounting and connection in rack-mounted or benchtop RF test environments.

RF Circulators And Isolators Replacement Considerations
