D3I4043-1

RF Circulators And Isolators Overview

The DiTom Microwave D3I4043-1 is a single-junction RF isolator designed for the 40.00 to 43.50 GHz frequency range. It features a Type-K female connector configuration and operates within a temperature range of -20°C to +65°C. The device supports an average forward power of 5 W, provides 18 dB isolation, and maintains a VSWR of 1.5. Its physical dimensions are 0.5 in x 0.5 in x 0.7 in, packaged in bulk.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high isolation in the E-band spectrum
• Engineered as a single-junction component for stable RF performance
• Constructed with Type-K connectors for secure waveguide interface integration

RF Circulators And Isolators Applications

• E-band microwave communication systems
• Point-to-point wireless links requiring signal directionality
• Test and measurement instrumentation setups

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender configuration against system requirements, as the D3I4043 series includes variants with different male/female arrangements. Confirm that the Type-K interface matches existing waveguide infrastructure. Ensure environmental ratings align with operational temperature constraints. Check current availability status as distribution may be limited or restricted in certain regions.

RF Circulators And Isolators Selection Notes

Select this model when a fixed 40-43.5 GHz isolator with 18 dB isolation is required. Compare against the D3C4043-1 circulator if bidirectional routing is needed instead of isolation. Consider the D3I4043Q-3 variant if a 2.4 mm connector interface is preferred over Type-K. Evaluate power handling limits relative to system peak levels.

RF Circulators And Isolators Part Context

This component belongs to the D3I4043 series of RF isolators from DiTom Microwave. It shares core specifications with sibling models like the D3I4043-2 and D3I4043-3, differing primarily in connector orientation. It complements the D3C4043-1 circulator within the same manufacturer's portfolio for E-band applications.
