D3I3570-1

RF Circulators And Isolators Overview

The D3I3570-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for the 3.5 GHz to 7.0 GHz frequency range. It features SMA-Female connectors and operates within a temperature range of 0°C to +50°C. Key electrical specifications include a minimum isolation of 17 dB, an insertion loss of 0.5 dB, and a VSWR of 1.35. The device supports an average forward power of 20 W and is housed in a module package with SMA connectors.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal transmission using a single-junction design
• Ensures high port-to-port isolation to protect source components
• Maintains low insertion loss for efficient signal integrity

RF Circulators And Isolators Applications

• Protecting microwave sources from reflected power
• Isolating stages in multi-stage amplifier chains
• Signal routing in radar and communication systems

RF Circulators And Isolators Procurement Notes

Verify that the specific part number matches the required connector configuration and performance parameters. Confirm compliance with RoHS3 standards and EAR99 classification for export purposes. Ensure the operating environment stays within the specified 0°C to +50°C temperature range to maintain rated isolation and power handling capabilities.

RF Circulators And Isolators Selection Notes

Select this component when a broadband isolator is needed between 3.5 GHz and 7.0 GHz. Consider the 20 W power rating and 17 dB isolation minimum for system protection requirements. The SMA-Female interface dictates the necessary cabling and adapter infrastructure for integration into existing RF test or production setups.

RF Circulators And Isolators Part Context

This model belongs to the D3I3570 series of RF isolators produced by DiTom Microwave. It shares the same core frequency band and physical dimensions as other variants in the family but is distinguished by its specific SMA-Female connector configuration and standardized electrical tolerances for general-purpose microwave applications.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative models from the same manufacturer only if they match the 3.5–7.0 GHz range, 20 W power rating, and SMA-Female interface without requiring mechanical redesign.
