ADT8-1T+

Balun Overview

The ADT8-1T+ is a surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 100 kHz to 130 MHz and provides a 1:8 impedance transformation ratio. The component is designed for 50-ohm systems and features a flat lead package style designated as CD637. It supports a maximum DC current of 30 mA and has a power rating of 500 mW. The device is RoHS compliant and suitable for applications requiring balanced-to-unbalanced signal conversion in the specified frequency band.

Balun Feature Summary

• Provides 1:8 impedance transformation ratio for balanced-to-unbalanced signal conversion
• Operates effectively across a wide frequency range from 100 kHz to 130 MHz
• Utilizes a core and wire construction method for reliable RF performance
• Designed with a surface-mount flat lead package for automated PCB assembly

Balun Applications

• RF and wireless communication systems requiring impedance matching
• Balanced-to-unbalanced signal conversion in receiver front-ends
• Antenna interface circuits for single-ended to differential signal processing
• Broadband RF amplifier input and output stages

Balun Procurement Notes

Verify that the specific order includes the '+' suffix, which indicates RoHS compliance and halogen-free status according to Mini-Circuits standards. Confirm the package type matches the CD637 flat lead specification for proper PCB land pattern design. Ensure that the operating environment does not exceed the 500 mW power rating or 30 mA DC current limit to maintain component integrity and performance stability.

Balun Selection Notes

Select this component when a 1:8 impedance transformation is required between 100 kHz and 130 MHz. Consider the surface-mount form factor if space constraints favor the CD637 package over through-hole alternatives. Evaluate the 50-ohm system compatibility to ensure proper integration with existing RF circuitry. Compare against other Mini-Circuits baluns if different transformation ratios or frequency ranges are needed for the specific application requirements.
