D4I1218-2

RF Circulators And Isolators Overview

The D4I1218-2 is a dual junction coaxial isolator manufactured by DiTom Microwave, designed for operation within the 12 GHz to 18 GHz frequency range. It features SMA-Female connectors and supports an average forward power of 10 W. Key electrical specifications include 40 dB isolation, 1 dB insertion loss, and a VSWR of 1.25. The component is housed in a module with SMA connectors, complies with RoHS3 standards, and has an MSL rating of 1.

RF Circulators And Isolators Feature Summary

• Dual junction design for enhanced performance
• Coaxial construction with SMA-Female interfaces
• High isolation capability of 40 dB

RF Circulators And Isolators Applications

• Space and defense satellite systems
• RF signal transmission paths requiring unidirectional flow
• Microwave measurement equipment

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration suffix against official DiTom documentation, as variants like -2 may denote distinct mechanical or pinout arrangements not implied by the base model number. Confirm environmental testing requirements such as thermal vacuum compatibility if intended for aerospace qualification. Ensure mating connectors match the SMA-Female specification to maintain impedance integrity.

RF Circulators And Isolators Selection Notes

Select this component when a 12–18 GHz isolator with 10 W power handling is required. The dual junction architecture provides superior isolation compared to single-junction designs. Verify that the SMA-Female interface aligns with system cabling. Consider the 1 dB insertion loss impact on overall link budget and ensure the module form factor fits the available chassis space.

RF Circulators And Isolators Part Context
