D4I3570-3

RF Circulators And Isolators Overview

The D4I3570-3 is a microwave isolator manufactured by DiTom Microwave, designed for operation within the 3.5 GHz to 7.00 GHz frequency range. This component features SMA-FEMALE connectors and is housed in a module package. It supports an average forward power of 20 W while maintaining a maximum insertion loss of 1.00 dB. The device provides a minimum isolation of 34 dB and achieves a voltage standing wave ratio (VSWR) of 1.35. These specifications ensure effective signal directionality and protection against reflected power in high-frequency RF systems.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high reverse isolation
• Operates across a broad 3.5 GHz to 7.00 GHz bandwidth
• Integrates SMA-FEMALE connectors for standard interface compatibility
• Handles up to 20 W average forward power

RF Circulators And Isolators Applications

• RF test and measurement equipment
• Microwave communication systems
• Radars and electronic warfare systems
• Satellite ground stations

RF Circulators And Isolators Procurement Notes

Verify the specific part number suffix against official DiTom Microwave documentation to confirm connector type and performance tolerances. Ensure that the required operating temperature range aligns with system environmental constraints. Confirm RoHS compliance status if restricted substances are prohibited in the final assembly. Cross-reference the datasheet electrical limits with actual system power levels to prevent component damage during procurement.

RF Circulators And Isolators Selection Notes

Select this model when high isolation is critical for protecting sensitive source components from reflected energy. The 34 dB isolation rating distinguishes it from lower-performance variants in the series. Consider the 20 W power handling capability relative to peak system loads. The SMA-FEMALE interface dictates mating cable requirements. Evaluate the 1.00 dB insertion loss impact on overall link budget efficiency before finalizing the design choice.

RF Circulators And Isolators Part Context

This component belongs to the D4I3570 series of microwave isolators produced by DiTom Microwave. The series covers frequencies from 3.5 GHz to 7.00 GHz. Variants within the family differ primarily in isolation levels and insertion loss characteristics. The D4I3570-3 represents a high-isolation option within this frequency band, utilizing ferrite materials for non-reciprocal signal propagation.

RF Circulators And Isolators Replacement Considerations

Direct substitutes include other models from the D4I3570 series with matching frequency ranges but potentially different isolation ratings. Verify mechanical dimensions and connector orientation before swapping. Alternative manufacturers may offer comparable performance but require full electrical re-validation.
