TCM2-33X+

Overview

The TCM2-33X+ is a surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 10 MHz to 3 GHz, providing impedance transformation from an unbalanced 50 Ohm port to a balanced 100 Ohm port (1:2 ratio). The component features a compact 6-SMD, flat lead package measuring 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 13.77 dB, and a phase difference of 4 degrees. It supports a maximum DC current of 30 mA and has a power rating of 400 mW. The device functions reliably between -40°C and +85°C.

Feature Summary

• Provides single-channel RF signal conversion between unbalanced and balanced circuits with a 1:2 impedance ratio.
• Engineered for high-frequency operation covering the 10 MHz to 3 GHz spectrum.
• Designed for direct surface-mount integration using a compact 6-SMD footprint.

Applications

• RF front-end circuitry in wireless communication systems
• Antenna interface matching networks
• Single-ended to differential signal conversion

Procurement Notes

Verify the specific suffix against official documentation to confirm exact performance characteristics, as variations may exist within the product line. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure that the selected packaging format aligns with automated placement equipment capabilities. Cross-reference the manufacturer's latest datasheet to validate pinout configurations and recommended PCB land patterns for optimal signal integrity.

Selection Notes

Select this component when a wideband solution is required for frequencies extending up to 3 GHz. The 1:2 impedance ratio makes it suitable for interfacing standard 50 Ohm systems with 100 Ohm differential lines. Consider the physical dimensions and thermal limits when designing for dense PCB layouts or environments with elevated operating temperatures. Evaluate insertion loss and return loss specifications against system budget requirements to ensure adequate signal transmission efficiency.
