MTX2-183+

Balun Overview

The Mini-Circuits MTX2-183+ is a wideband MMIC balun transformer die designed for RF applications. It operates within a frequency range of 2 to 18 GHz and provides an impedance ratio of 1:2. The component features low insertion loss, typically 2.0 dB, and excellent phase unbalance, typically 2 degrees. It is housed in a 12-VQFN package with an exposed pad, suitable for surface-mount integration.

Balun Feature Summary

• Wideband operation from 2 to 18 GHz
• 1:2 impedance transformation ratio
• Low insertion loss and amplitude unbalance
• Excellent phase balance performance

Balun Applications

• Instrumentation systems
• WLAN infrastructure
• WiMAX and WiBRO networks
• Radar systems

Balun Procurement Notes

Verify the specific suffix designation when ordering, as variants such as MTX2-183-D+ exist. Confirm that the selected part matches the required package type and application frequency range. Ensure compatibility with the target PCB layout for the VQFN exposed pad connection.

Balun Selection Notes

Select this component for designs requiring broad bandwidth coverage up to 18 GHz. Consider the 1:2 impedance ratio for single-ended to differential signal conversion. Evaluate thermal management requirements due to the exposed pad design and ensure the operating environment supports the specified frequency range.

Balun Part Context

This device belongs to the Mini-Circuits MTX2 family of MMIC balun transformers. These components are engineered for high repeatability and consistent performance across the specified ultra-wideband spectrum. They serve as critical passive elements in modern RF front-end architectures.

Balun Replacement Considerations

Public confirmed substitute part numbers include NCR2-183+ and MTX2-183-D+. Verify electrical specifications and pinout compatibility before substitution.
