ADT4-1WT+

Balun Overview

The ADT4-1WT+ is a surface-mount RF transformer manufactured by Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 2 MHz to 775 MHz and features a 1:4 impedance ratio with a nominal 50Ω system impedance. The component utilizes a core and wire construction housed in a CD542 case style (SMD-6P, 7.9x5.6mm). It provides excellent return loss and amplitude unbalance performance, making it suitable for high-frequency applications requiring precise signal balancing.

Balun Feature Summary

• Core and wire construction for robust RF signal transformation
• Optimized for low amplitude unbalance and high return loss
• Surface mount design compatible with automated assembly processes

Balun Applications

• RF balanced-to-unbalanced (balun) conversion circuits
• Antenna feed line matching networks
• Differential signal routing in communication systems

Balun Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors. Ensure that the package dimensions and pin configuration match the target PCB footprint requirements. Confirm that the operating temperature range aligns with the environmental conditions of the intended application before finalizing procurement.

Balun Selection Notes

Select this component when a 1:4 impedance transformation is required between 2 MHz and 775 MHz. Consider the SMD form factor for space-constrained designs. Evaluate the amplitude unbalance and return loss specifications against the system's tolerance levels to ensure signal integrity is maintained throughout the operational bandwidth.

Balun Part Context

This part belongs to the ADT series of broadband transformers from Mini-Circuits, which are widely used in RF and microwave engineering. The series offers various impedance ratios and frequency ranges, with the ADT4-1WT+ specifically addressing mid-band RF applications requiring balanced output signals.

Balun Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers. Cross-reference electrical parameters such as frequency range, impedance ratio, and insertion loss to ensure functional compatibility without altering circuit performance.
