ADT1.5-122+

Balun Overview

The ADT1.5-122+ is a surface-mount RF balun manufactured by Mini-Circuits, designed for radio frequency applications. It operates within a frequency range of 20 MHz to 1.2 GHz and provides a 1:1.5 impedance transformation ratio. The component utilizes core and wire transformer technology and is housed in a compact 6-SMD, flat lead package. Electrical specifications include an amplitude balance ranging from ±0.01 dB to 0.95 dB and a phase balance between 0.03 degrees and 5.58 degrees across the operational bandwidth.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion using core and wire transformer architecture
• Supports wideband operation from 20 MHz to 1.2 GHz
• Designed for surface mount integration with a compact footprint

Balun Applications

• RF wireless communication systems
• Balanced circuit interfacing
• Signal distribution networks

Balun Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update electrical characteristics or mechanical drawings over time. Confirm that the '+ ' suffix indicates compliance with current RoHS directives. Ensure the selected package variant matches the PCB layout requirements for 6-SMD flat leads. Cross-reference the impedance ratio and frequency limits against the system design specifications before finalizing procurement.

Balun Selection Notes

Select this component when a 1:1.5 impedance transformation is required within the 20 MHz to 1.2 GHz band. Consider the amplitude and phase balance tolerances to ensure they meet the system's linearity requirements. Evaluate the surface-mount form factor against available board space constraints. Compare performance metrics against alternative baluns if tighter phase balance or broader frequency coverage is necessary for the specific application.
