D3I7012-3

RF Circulators And Isolators Overview

The DiTom Microwave D3I7012-3 is a single-junction RF isolator designed for operation within the 7.00 to 12.40 GHz frequency range. It features SMA female connectors and is housed in a module format with dimensions of 0.86 inches by 0.5 inches by 0.98 inches. The component supports an average forward power of 25 W, providing 18 dB of isolation. Key electrical specifications include a maximum insertion loss of 0.5 dB and a voltage standing wave ratio (VSWR) of 1.3. It operates reliably between -30°C and +85°C.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high reverse isolation
• Supports continuous average forward power handling up to 25 watts
• Utilizes SMA female connector interface for standard integration
• Constructed as a single-junction module for compact deployment

RF Circulators And Isolators Applications

• RF front-end modules requiring signal directionality
• Test and measurement instrumentation systems
• Microwave communication link protection circuits
• Satellite ground station receiver chains

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version for the D3I7012-3 to confirm current RoHS compliance status and exact mechanical tolerances. Ensure that the SMA female connector configuration matches the system requirements. Check for any recent manufacturing updates or pinout revisions before finalizing procurement orders. Confirm availability through authorized distributors as supply levels may vary.

RF Circulators And Isolators Selection Notes

Select this component when a 7 to 12.4 GHz operating band is required with moderate power handling capabilities. The 25 W average power rating suits applications where thermal management is feasible. Compare the 18 dB isolation specification against system noise floor requirements. Ensure the SMA female interface aligns with existing cable assemblies and fixture designs.

RF Circulators And Isolators Part Context

This part belongs to the D3I7012 series from DiTom Microwave, which includes various isolator and circulator variants. The series covers the same 7 to 12.4 GHz frequency range but differs in function and connector types. Other models in the family include circulators like the D3C7012 series, offering different port configurations while maintaining similar electrical performance metrics.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include other D3I7012 variants with matching SMA female connectors. Verify that alternative parts maintain the 25 W power rating and 18 dB isolation level. Cross-reference mechanical dimensions to ensure fitment in existing enclosures. Confirm that replacement components support the same -30°C to +85°C operating temperature range.
