D3I5964

RF Circulators And Isolators Overview

The D3I5964 is a single junction RF isolator manufactured by DiTom Microwave, designed for operation within the 5.9 GHz to 6.4 GHz frequency range. It features SMA female connectors on both input and output ports, housed in a module package measuring 0.62 inches by 0.5 inches by 0.78 inches. The component supports an average forward power of 20 W with a maximum insertion loss of 0.3 dB and a voltage standing wave ratio (VSWR) of 1.15. Isolation performance reaches 23 dB. The device operates reliably between -30°C and +65°C.

RF Circulators And Isolators Feature Summary

• Single junction coaxial design for unidirectional signal transmission
• SMA female connector configuration for standard RF interfacing
• Low insertion loss characteristics ensuring minimal signal attenuation
• Robust thermal stability across extended industrial temperature ranges

RF Circulators And Isolators Applications

• RF signal routing in microwave communication systems
• Protection of sensitive transmitter components from reflected power
• Integration into radar system signal chains
• Test and measurement equipment requiring stable isolation

RF Circulators And Isolators Procurement Notes

Verify the specific ordering suffix when sourcing replacements, as variations such as the D3I5964-3 may exist with identical core specifications but distinct packaging or minor form factor adjustments. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to final procurement decisions. Ensure that the required SMA female interface matches the existing system architecture to avoid adapter requirements. Cross-reference the part number against the latest official datasheet to confirm current production status and availability constraints.

RF Circulators And Isolators Selection Notes

Select this component when a fixed frequency band between 5.9 GHz and 6.4 GHz is required for high-power isolation applications. The 20 W average power rating makes it suitable for moderate to high power transmitters where protection against load mismatches is critical. Consider the physical dimensions of 0.62 x 0.5 x 0.78 inches for board space planning. The SMA female interface dictates the mating cable or fixture type. Evaluate the 23 dB isolation specification against system noise floor requirements to ensure adequate reverse signal suppression.

RF Circulators And Isolators Part Context

This model belongs to the DiTom Microwave series of RF circulators and isolators, specifically engineered for microwave frequency bands. The product line focuses on single junction designs that provide reliable non-reciprocal signal flow. These components are typically utilized in environments demanding stable performance under varying thermal conditions. The D3I5964 represents a standard coaxial solution within this portfolio, balancing electrical performance with mechanical durability for professional RF engineering applications.

RF Circulators And Isolators Replacement Considerations

The D3I5964-3 is a confirmed substitute variant within the same family, sharing the 5.9–6.4 GHz frequency range and SMA female interface. Verify if the specific suffix indicates any changes in packaging or minor dimensional tolerances before swapping. Ensure that the replacement maintains the 20 W power handling and 23 dB isolation metrics required by the original circuit design.
