TCW2-133+

Balun Overview

The TCW2-133+ is a 1:2 LTCC SMT transformer designed for signal conditioning in the 7 to 13 GHz frequency range. It features a 50 Ohm impedance and operates within a temperature range of -55°C to +125°C. The component has an insertion loss of 1 dB, amplitude unbalance of 1.7 dB, and phase unbalance of 13 degrees. It supports a maximum RF input power of 2W at 25°C. The device is housed in a compact 1.6 mm x 0.79 mm x 0.61 mm package with SMD/SMT termination.

Balun Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides balanced-to-unbalanced signal conversion with a 1:2 impedance ratio
• Engineered for high-frequency operation up to 13 GHz
• Supports surface-mount installation for automated assembly

Balun Applications

• S-band wireless communication systems

Balun Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before integration. Confirm that the operating environment remains within the specified -55°C to +125°C thermal limits. Ensure PCB layout accommodates the precise 1.6 mm x 0.79 mm x 0.61 mm footprint. Validate that the 2W maximum RF input power rating is not exceeded during peak operation to prevent component damage.

Balun Selection Notes

Select this component when a compact 1:2 balun is required for frequencies between 7 and 13 GHz. It is suitable for designs prioritizing low insertion loss and tight phase balance. Consider the LTCC construction for stability in varying thermal conditions. Ensure the application can accommodate the small SMD package dimensions and surface-mount processing requirements.

Balun Part Context
