ADT1.5-17+

Balun Overview

The ADT1.5-17+ is a surface-mount RF transformer manufactured by Mini-Circuits, designed for broadband applications. It operates within a frequency range of 0.5 MHz to 1700 MHz and provides an impedance ratio of 1:1.5. The component utilizes a compact 060803 package with six flat leads for SMD/SMT termination. Key electrical specifications include a primary impedance of 50 Ohms. Typical insertion loss values are approximately 0.65 dB at 0.5 MHz and 0.35 dB at 51 MHz. Isolation performance ranges from 17.56 dB at 0.5 MHz to 24.57 dB at 51 MHz.

Balun Feature Summary

• Wideband operation spanning from 0.5 MHz to 1700 MHz
• Compact 060803 surface-mount package design
• Integrated 50 Ohm primary impedance configuration

Balun Applications

• RF signal balancing and unbalancing circuits
• Broadband impedance matching networks
• Mixed-signal interface isolation

Balun Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure compliance with current RoHS and REACH standards. Confirm that the 060803 footprint matches your PCB layout requirements. Cross-reference the datasheet version number to validate the latest electrical performance curves and mechanical dimensions before finalizing procurement orders.

Balun Selection Notes

Select this component when a wide bandwidth covering HF to UHF bands is required in a minimal footprint. The 1:1.5 impedance ratio suits specific transformation needs differing from standard 1:1 or 1:9 configurations. Ensure the operating environment remains within the specified temperature range and that the low insertion loss characteristics align with system sensitivity requirements.

Balun Part Context

This part belongs to the Mini-Circuits ADT series of broadband transformers, which are engineered for high-performance RF applications. The series offers various impedance ratios and package styles to accommodate different circuit constraints. The ADT1.5-17+ specifically addresses needs for moderate impedance transformation in ultra-compact surface-mount designs.

Balun Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Generic equivalents may not replicate the precise 0.5 to 1700 MHz bandwidth or the specific 060803 mechanical profile. Validate any substitute against the original datasheet parameters to maintain circuit integrity.
