D3I1218-2

RF Circulators And Isolators Overview

The DiTom Microwave D3I1218-2 is a broadband RF isolator designed for operation within the 12 GHz to 18 GHz frequency range. This component features SMA-Female connectors and utilizes a module package configuration. It supports an average forward power of 15 W while maintaining a maximum insertion loss of 0.5 dB. The device provides 20 dB of isolation and exhibits a voltage standing wave ratio (VSWR) of 1.25. It complies with RoHS3 standards and carries an ECCN classification of EAR99.

RF Circulators And Isolators Feature Summary

• Provides directional signal transmission in the 12 GHz to 18 GHz band
• Features SMA-Female connector interface for modular integration
• Supports high average forward power handling capabilities

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal directionality
• Test and measurement equipment interfaces
• Radar system components

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official DiTom Microwave documentation to confirm functional equivalence, as ordering suffixes may indicate variations in mechanical or electrical specifications not evident from general descriptions. Ensure compatibility with SMA-Female mating connectors and validate that the 15 W power rating aligns with system thermal requirements. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly.

RF Circulators And Isolators Selection Notes

Select this component when a fixed-frequency isolator is required for the K-band spectrum. The 1.25 VSWR indicates efficient impedance matching suitable for sensitive receiver protection. Consider the module form factor for PCB or chassis mounting constraints. Evaluate the 0.5 dB insertion loss impact on overall system noise figure and gain budget before implementation in low-noise amplifier chains.

RF Circulators And Isolators Part Context

The D3I1218-2 belongs to the D3I1218 series of broadband and narrowband connectorized RF isolators manufactured by DiTom Microwave. This series includes variants such as the D3I1218 and related circulator models like the D3C1218 series. These components are engineered for microwave applications requiring robust signal isolation and are typically supplied in bags as standard packaging units.

RF Circulators And Isolators Replacement Considerations

The base model D3I1218 shares identical core specifications including frequency, power, and isolation ratings. Verify if the suffix '-2' denotes a specific manufacturing revision or testing standard rather than a functional difference. Cross-reference with D3C1218 series parts only if circulator functionality is acceptable, noting the distinct port configurations between isolators and circulators.
