TCN4-22+

Overview

The TCN4-22+ is a ceramic LTCC balun RF transformer manufactured by Mini-Circuits. It operates within a frequency range of 1200 to 2200 MHz, providing a 1:4 impedance transformation ratio with a nominal 50 Ohm system impedance. The component features an SMD no-lead package and supports a maximum RF power rating of up to 5 W. It is constructed using Low Temperature Co-fired Ceramic (LTCC) technology, ensuring aqueous washability and compliance with RoHS3 standards for environmental safety.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) construction for robust performance
• Provides balanced-to-unbalanced signal conversion with 1:4 impedance transformation
• Supports aqueous cleaning processes compatible with standard assembly lines
• Complies with RoHS3 environmental regulations

Applications

• S-band frequency upconverter assemblies
• RF sensing and connectivity layers in automotive systems
• ADAS and autonomous driving radar applications
• Smart access and keyless entry modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the LTCC construction meets the thermal requirements of the intended assembly process. Ensure the 5 W power rating aligns with the peak RF power levels in the target circuit design to prevent component degradation.

Selection Notes

Select this component when a compact, high-frequency solution is required for S-band applications. The 1:4 transformation ratio makes it suitable for driving differential loads from single-ended sources. Verify that the 1200-2200 MHz operational bandwidth covers the entire signal spectrum of the application without requiring additional filtering stages.

Part Context

This part belongs to the Mini-Circuits TCN4 series of ceramic baluns. These components are designed for high-reliability RF applications where size constraints and performance stability are critical. The series utilizes advanced LTCC technology to achieve consistent electrical characteristics across wide temperature ranges.
