D3I1020-3

RF Circulators And Isolators Overview

The D3I1020-3 is a single junction coaxial RF isolator manufactured by DiTom Microwave, designed for operation within the K-band frequency spectrum. It provides a functional bandwidth spanning from 10 GHz to 20 GHz, ensuring stable signal transmission across this high-frequency range. The component features SMA female connectors on both input and output ports, facilitating straightforward integration into standard microwave test setups and communication systems. Key electrical specifications include an insertion loss of 0.7 dB, an isolation level of 16 dB, and a voltage standing wave ratio (VSWR) of 1.4. The device supports an average forward power handling capacity of 10 W, making it suitable for moderate power applications in radar and electronic warfare environments.

RF Circulators And Isolators Feature Summary

• Single junction coaxial design ensures reliable unidirectional signal flow with minimal reflection
• SMA female connector configuration allows direct compatibility with standard microwave interconnects
• High isolation performance effectively suppresses reflected signals to protect source components
• Robust construction supports continuous operation under specified average power loads

RF Circulators And Isolators Applications

• Microwave measurement and test instrumentation setups requiring signal directionality
• Radar system transmitter chains for protecting sensitive oscillator sources
• Electronic countermeasure equipment utilizing K-band frequency ranges
• Satellite communication ground station uplink modules

RF Circulators And Isolators Procurement Notes

Verify that the specific part number suffix matches the required connector type and mechanical dimensions before ordering. Confirm compliance with RoHS3 standards if environmental regulations apply to your project. Ensure that the receiving facility has appropriate ESD protection protocols, as RF components are sensitive to electrostatic discharge. Cross-reference the manufacturer's datasheet for detailed mounting torque specifications and surface finish requirements to guarantee optimal RF performance and long-term reliability in your assembly process.

RF Circulators And Isolators Selection Notes

Select this model when a fixed frequency range between 10 GHz and 20 GHz is required without tunability. The SMA interface is ideal for benchtop testing or semi-rigid cable connections rather than permanent PCB integration. Consider the 10 W power rating against your system's peak and average power levels to prevent thermal damage. If higher isolation or lower insertion loss is critical, compare alternative models within the same product family, noting that variations may exist in physical footprint or connector gender.

RF Circulators And Isolators Part Context

This component belongs to the D3I1020 series of coaxial isolators produced by DiTom Microwave. The series shares common core technologies regarding magnetic material selection and junction geometry, differing primarily in connector configurations and minor mechanical tolerances. Variants such as D3I1020-1 and D3I1020-2 offer similar electrical characteristics but may feature different packaging or connector styles. This specific model represents a standardized solution for K-band applications where SMA connectivity is preferred for ease of use and widespread availability in laboratory environments.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same manufacturer line include D3I1020-1 and D3I1020-2, which share identical electrical specifications but may differ in connector orientation or mechanical housing details. When replacing, verify that the physical dimensions and connector gender match the existing board layout or cable assembly. Ensure that any cross-manufacturer replacement maintains equivalent VSWR and isolation ratings to preserve system stability.
