TCW2-392+

Overview

The TCW2-392+ is a 1:2 LTCC balun transformer manufactured by Mini-Circuits, designed for RF applications within the 3.3 GHz to 3.9 GHz frequency range. It features a 50Ω impedance configuration and utilizes a compact 0603 (1608 Metric) surface-mount package with six pads. The component exhibits a maximum insertion loss of 1.0 dB, a minimum return loss of 13.67 dB, and a phase difference of 5°. It operates in compliance with RoHS3 standards and carries an EAR99 classification.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) construction for stable RF performance
• Provides balanced-to-unbalanced signal conversion with a 1:2 impedance ratio
• Designed for high-frequency S-band operations between 3.3 GHz and 3.9 GHz

Applications

• S-band upconverter designs
• RF front-end modules requiring impedance transformation
• Wireless communication infrastructure components

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format, such as tape-and-reel or cut tape, matches your assembly requirements. Confirm that the component's RoHS3 compliance status aligns with your environmental regulations. Cross-reference the manufacturer part number with official datasheets to validate electrical specifications before integration into production lines.

Selection Notes

Select this component when a 1:2 impedance transformation is required in the 3.3–3.9 GHz band. The 0603 footprint suits space-constrained PCB layouts. Ensure the design accommodates the specified insertion loss and return loss limits. Verify thermal management capabilities for surface-mount installation processes compatible with standard reflow profiles.

Part Context
