MTX2-133+

Balun Overview

The MTX2-133+ is a wideband MMIC balun transformer manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates within a frequency range of 1.5 GHz to 13 GHz and features a 1:2 impedance ratio with a nominal system impedance of 50 Ohms. The component is housed in a compact 12-VQFN package with an exposed pad, suitable for surface-mount technology. Key electrical specifications include a typical insertion loss of 2.2 dB and excellent phase unbalance of approximately 2 degrees. The device supports board mounting and is intended for high-performance microwave circuits requiring balanced-to-unbalanced conversion.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion with a 1:2 impedance transformation ratio
• Operates as a wideband MMIC transformer covering frequencies from 1.5 GHz to 13 GHz
• Delivers low insertion loss and minimal amplitude and phase unbalance for signal integrity

Balun Applications

• S-band upconverter designs
• RF front-end modules requiring impedance matching
• Microwave communication systems

Balun Procurement Notes

Verify the specific datasheet version and ordering suffixes when sourcing, as Mini-Circuits may offer variations in packaging or testing criteria. Confirm that the 12-VQFN footprint matches your PCB layout constraints. Ensure compatibility with the 1.5–13 GHz operational range for your specific application requirements before finalizing procurement decisions.

Balun Selection Notes

Select this component when a wideband MMIC solution is required for balanced-to-unbalanced conversion between 1.5 GHz and 13 GHz. The MTX2-133+ is appropriate for designs prioritizing low insertion loss and tight phase balance over a broad spectrum. Consider the 12-VQFN package size and thermal pad requirements during the initial schematic capture and layout phases to ensure proper integration.

Balun Part Context

The MTX2-133+ belongs to the MTX2 series of MMIC balun transformers from Mini-Circuits. This series is engineered for high repeatability and performance in RF and microwave applications. The component serves as a critical interface for converting single-ended signals to differential signals or vice versa, maintaining signal fidelity across a significant portion of the S-band and extending into higher microwave frequencies.
