ADTT4-1+

Balun Overview

The ADTT4-1+ is an RF balun manufactured by Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 200 kHz to 120 MHz and features a 1:4 impedance transformation ratio. The component utilizes a core and wire transformer construction with six surface-mount flat leads. It is specified for a nominal 50-ohm system impedance, ensuring efficient signal transfer across its designated bandwidth while maintaining phase balance.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion functionality
• Utilizes core and wire transformer construction for reliable performance
• Features six surface-mount flat lead configuration for PCB integration

Balun Applications

• RF signal balancing in communication systems
• Impedance matching between 50-ohm unbalanced and balanced circuits
• Audio and signal transformer applications within the specified frequency range

Balun Procurement Notes

Verify the specific datasheet revision (e.g., ED-7831/2) when sourcing components to ensure alignment with current manufacturing specifications. Confirm that the supplier provides official Mini-Circuits documentation to validate the 1:4 ratio and frequency range parameters. Cross-reference the package type against design requirements to ensure compatibility with the six flat lead footprint.

Balun Selection Notes

Select this component when a 1:4 impedance transformation is required between 200 kHz and 120 MHz. Ensure the application demands a core and wire construction rather than ceramic alternatives. Verify that the surface-mount flat lead package fits the available PCB real estate and soldering capabilities.

Balun Part Context

This part belongs to Mini-Circuits' line of RF transformers and baluns. It serves as a specialized solution for low-frequency RF applications requiring balanced outputs. The model distinguishes itself through its specific 1:4 ratio and wideband operation compared to narrow-band or different-ratio variants in the manufacturer's portfolio.

Balun Replacement Considerations

Direct substitutes include other Mini-Circuits models with identical 1:4 ratios and similar frequency ranges, such as the T4-1+. Verify pinout compatibility and physical dimensions before swapping to ensure mechanical fit on the existing circuit board.
