ADT1.5-1+

Balun Overview

The ADT1.5-1+ is a surface-mount RF balun manufactured by Mini-Circuits, designed for broadband applications within the 0.5 MHz to 650 MHz frequency range. This component features a 1:1.5 impedance transformation ratio and operates with a nominal 50Ω system impedance. It utilizes a CD542 case style package with six SMD flat leads, measuring approximately 7.9mm in length and 5.6mm in width. The device is RoHS compliant and supports operation across a temperature range of -55°C to +100°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion with a fixed 1:1.5 impedance ratio
• Supports wideband RF signal transmission from 0.5 MHz up to 650 MHz
• Utilizes a compact surface-mount package with flat leads for automated assembly

Balun Applications

• RF front-end circuitry requiring impedance matching
• Balanced antenna interface connections
• Broadband signal distribution networks

Balun Procurement Notes

Verify that the ordering suffix '+' indicates compliance with current environmental standards, as specified by the manufacturer. Confirm the specific package variant matches the required PCB land pattern for the CD542 form factor. Ensure the selected component meets the operational temperature requirements for the intended application environment before finalizing procurement.

Balun Selection Notes

Select this component when a 1:1.5 impedance transformation is required for frequencies extending up to 650 MHz. Consider the surface-mount footprint dimensions against available board space. Evaluate insertion loss and return loss performance curves if precise signal integrity metrics are critical for the design.

Balun Part Context

This part belongs to the ADT series of core and wire transformers produced by Mini-Circuits. These components are engineered for high reliability in RF and microwave circuits. The ADT1.5-1+ specifically addresses applications needing a moderate impedance step-up or step-down ratio within a standard 50Ω infrastructure.

Balun Replacement Considerations

Direct substitutes include other Mini-Circuits models such as the ADT1-1WT or ADT1-6T, which offer different impedance ratios but share similar construction styles. Verify electrical specifications and physical dimensions before swapping.
