TCML1-19X+

Balun Overview

The TCML1-19X+ is an RF transformer manufactured by Mini-Circuits, designed for operation within the frequency range of 800 MHz to 1.9 GHz. It functions as a balun with 50 Ohm unbalanced and balanced impedances. The component utilizes a surface-mount package configuration featuring six flat leads. Key electrical specifications include a maximum insertion loss of 3 dB and a minimum return loss of 5.94 dB. The device is constructed using materials compliant with RoHS3 standards and carries an EAR99 export classification code.

Balun Feature Summary

• Provides signal transformation between unbalanced and balanced circuits within the specified microwave frequency band
• Utilizes a compact surface-mount footprint suitable for automated assembly processes
• Maintains impedance matching at 50 Ohms for both ports to ensure efficient signal transfer

Balun Applications

• RF front-end modules in wireless communication systems
• Signal conditioning in industrial control equipment
• Balanced-to-unbalanced conversion in test and measurement instrumentation

Balun Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to confirm packaging details and tape-and-reel specifications. Ensure that the requested variant matches the required frequency range and impedance parameters for the intended circuit design. Cross-reference the part number with current datasheets to confirm availability status and compliance certifications prior to finalizing purchase orders.

Balun Selection Notes

Select this component when a broadband balun solution is required for frequencies extending up to 1.9 GHz. Consider the physical dimensions of the six-flat-lead SMD package to ensure compatibility with the printed circuit board layout constraints. Evaluate the insertion loss and return loss specifications against system sensitivity requirements to determine suitability for low-loss signal path applications.

Balun Part Context

This component belongs to the Mini-Circuits portfolio of radio frequency and microwave passive devices. The manufacturer specializes in signal processing components ranging from DC to high microwave frequencies. The TCML1-19X+ represents a standard offering in their transformer lineup, designed for integration into various electronic systems requiring impedance transformation and signal balancing capabilities.

Balun Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternative part numbers. Direct replacements must match the operational frequency range, impedance values, and physical package dimensions to maintain circuit performance integrity without redesign.
