MTX2-143+

Balun Overview

The MTX2-143+ is a wideband MMIC balun transformer manufactured by Mini-Circuits, designed for RF applications. It operates within a frequency range of 5.5 GHz to 13.5 GHz and features an impedance ratio of 1:2 (non-balanced to balanced). The device utilizes IPD工艺技术 and is housed in a compact 12-VQFN exposed pad surface-mount package. Key electrical specifications include a maximum insertion loss of 2.5 dB, minimum return loss of 7.87 dB, and phase balance of 8 degrees. It supports operation across a temperature range consistent with standard commercial grades and is RoHS compliant.

Balun Feature Summary

• Wideband operation covering 5.5 GHz to 13.5 GHz
• Low insertion loss and amplitude unbalance characteristics
• Compact 12-VQFN surface-mount packaging

Balun Applications

• WiMAX systems
• Radar applications
• SATCOM links

Balun Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package type and tape/reel configuration. Confirm that the 12-VQFN exposed pad footprint matches the PCB design requirements. Check for any recent updates to the RoHS status or environmental compliance declarations prior to final procurement authorization.

Balun Selection Notes

Select this component when a wideband 1:2 impedance transformation is required between 5.5 GHz and 13.5 GHz. Consider its low insertion loss profile for signal integrity preservation. Ensure the design accommodates the exposed pad thermal management requirements inherent to the VQFN package style.

Balun Part Context

This part belongs to Mini-Circuits' line of integrated passive devices (IPD) and MMIC transformers. It serves as a bridge between single-ended and differential RF paths, replacing discrete transformer solutions with a monolithic, space-saving alternative suitable for high-frequency circuit boards.
