D3I4450-2

RF Circulators And Isolators Overview

The DiTom Microwave D3I4450-2 is a single-junction RF isolator designed for the 4.4 GHz to 5.0 GHz frequency range. It features SMA-FEMALE connectors and operates within a temperature range of -30°C to +60°C. Key electrical specifications include an average forward power rating of 20 W, isolation of 23 dB, insertion loss of 0.3 dB, and a VSWR of 1.15. The component is housed in a module with SMA connectors.

RF Circulators And Isolators Feature Summary

• Provides signal isolation in the 4.4 to 5.0 GHz band
• Utilizes SMA-FEMALE connector configuration
• Supports 20 W average forward power handling

RF Circulators And Isolators Applications

• RF circuit protection against reflected signals
• Transmitter output stage isolation
• Receiver input protection

RF Circulators And Isolators Procurement Notes

Verify the specific suffix '-2' against official DiTom Microwave documentation to confirm connector orientation or pinout variations, as suffixes often denote mechanical differences rather than functional changes. Ensure compatibility with existing SMA-FEMALE interfaces and validate thermal management requirements for the specified 20 W power rating during integration.

RF Circulators And Isolators Selection Notes

Select this component when precise isolation is required in the 4.4–5.0 GHz spectrum. Consider the 0.3 dB insertion loss impact on system gain and the 1.15 VSWR for impedance matching efficiency. Evaluate the module package dimensions (1 in x 0.5 in x 1 in) for spatial constraints and verify RoHS3 compliance if environmental regulations apply.

RF Circulators And Isolators Part Context

This model belongs to the D3I4450 series of RF isolators from DiTom Microwave. It shares core specifications with variants like D3I4450-3 but differs in suffix designation. The series targets applications requiring robust signal directionality and low loss in microwave communication systems.

RF Circulators And Isolators Replacement Considerations

D3I4450-3 is a documented variant within the same series. Verify mechanical and electrical equivalence before substitution.
