TCM2-43X+

Overview

The TCM2-43X+ is a surface-mount RF balun transformer manufactured by Mini-Circuits, designed for high-frequency signal conversion. It operates within a frequency range of 10 MHz to 4 GHz and features a 1:2 impedance transformation ratio between unbalanced and balanced ports. The component utilizes a 6-SMD module package with dimensions of 4.06 mm x 3.81 mm x 4.06 mm. Key electrical specifications include a maximum insertion loss of 3 dB, a minimum return loss of 14.98 dB, and a phase difference of 7°. It supports a maximum DC current of 30 mA and has a power rating of 400 mW. The device functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides single-channel RF signal conversion between unbalanced and balanced configurations
• Engineered for surface-mount integration into compact electronic assemblies
• Maintains stable performance characteristics across wideband microwave frequencies

Applications

• RF front-end circuitry in wireless communication systems

Procurement Notes

Verify the specific manufacturer part number against official Mini-Circuits documentation to ensure authenticity. Confirm that the received components match the specified 6-SMD package and RoHS compliance status. Check datasheet revisions for any updates to electrical parameters or recommended PCB land patterns prior to final implementation.

Selection Notes

Select this component when a 1:2 impedance transformation is required for signals between 10 MHz and 4 GHz. Ensure the design accommodates the 6-SMD footprint and thermal requirements for a 400 mW power rating. Consider the 7° phase difference specification if precise phase alignment is critical for the application's signal integrity.
