D3I4043Q-1

RF Circulators And Isolators Overview

The D3I4043Q-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 40.00 GHz to 43.50 GHz frequency range. It utilizes 2.4mm female connectors and features a module package with dimensions of 0.5 in x 0.5 in x 0.7 in. The component supports an average forward power of 5 W, provides 18 dB isolation, exhibits 1.2 dB insertion loss, and maintains a VSWR of 1.5. It operates between -20°C and +65°C.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission to protect source components from reflected energy
• Engineered for high-frequency millimeter-wave applications using 2.4mm interface
• Single junction design ensures stable performance across the specified bandwidth

RF Circulators And Isolators Applications

• Millimeter-wave radar systems
• Satellite communication transponders
• Point-to-point microwave links

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and mechanical drawing against project requirements before ordering. Confirm that the 2.4mm mating interfaces are compatible with existing test fixtures or system assemblies. Ensure environmental ratings meet operational temperature constraints. Request updated datasheets directly from DiTom Microwave to validate current manufacturing specifications and RoHS compliance status prior to final procurement decisions.

RF Circulators And Isolators Selection Notes

Select this model when a dedicated isolator is required for the 40-43.5 GHz band rather than a circulator. Compare insertion loss and isolation metrics against system noise budget requirements. Ensure the 5 W power handling capacity aligns with peak transmitter outputs. Verify physical space constraints fit the 0.5 in x 0.5 in footprint. Consider the 2.4mm connector type for compatibility with standard millimeter-wave test equipment and interconnects.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D3I series of RF isolators. It shares the same frequency range and core electrical specifications as the D3C4043-1 circulator but functions as a two-port device rather than a three-port network. The Q suffix typically denotes specific connector or material variations within the product line, requiring verification against official documentation for precise mechanical details.
