D3I0405-3

RF Circulators And Isolators Overview

The D3I0405-3 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 400 MHz to 500 MHz frequency range. It features SMA female connectors on both ports and supports an average forward power of 300 W. Key electrical specifications include an isolation of 16 dB, insertion loss of 0.5 dB, and a voltage standing wave ratio (VSWR) of 1.4. The device operates between -20°C and +65°C and measures 2.5 inches by 0.73 inches by 2.5 inches.

RF Circulators And Isolators Feature Summary

• Provides signal isolation in the 400 MHz to 500 MHz band
• Supports high average forward power handling
• Utilizes SMA female connector interfaces

RF Circulators And Isolators Applications

• RF signal transmission systems requiring directionality
• Test and measurement equipment setups
• Microwave communication links

RF Circulators And Isolators Procurement Notes

Verify component authenticity through authorized DiTom Microwave distributors or certified suppliers. Confirm RoHS compliance status and specific datasheet revisions prior to ordering. Ensure connector compatibility with existing SMA female interfaces. Validate thermal management requirements against the specified operating temperature range of -20°C to +65°C. Request official documentation to confirm performance parameters match application needs.

RF Circulators And Isolators Selection Notes

Select this model when a single-junction isolator is required for frequencies between 400 MHz and 500 MHz. Consider the 300 W power rating and 16 dB isolation level for system design. Ensure physical dimensions fit the enclosure space. Verify that SMA female connectors align with system interconnect standards. Compare VSWR and insertion loss values against system sensitivity requirements.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D3I0405 series of RF isolators. It shares the same frequency range and basic form factor with related models like the D3C0405-1 circulator, though it functions as an isolator rather than a circulator. The series targets applications needing reliable signal directionality in the VHF/UHF bands.

RF Circulators And Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-reference options based on matching frequency, power, and connector specifications from other manufacturers if direct replacement is necessary.
