TCW1-272+

Overview

The TCW1-272+ is a 1:1 impedance ratio LTCC transformer designed for RF applications. It operates within a frequency range of 1700 MHz to 2700 MHz, providing a bandwidth of 900 MHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination type. It is housed in a JC0603C package, equivalent to the 0402 metric size. The device supports board mount installation and functions reliably across a temperature range from -55°C to +125°C.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for compact integration
• Provides balanced-to-unbalanced signal transformation with a 1:1 impedance ratio
• Supports surface mount assembly via the JC0603C footprint

Applications

• Wireless communications systems
• RF front-end modules
• Balanced antenna interfaces

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update specifications over time. Confirm that the JC0603C package dimensions align with your PCB layout constraints. Ensure the operating temperature range of -55°C to +125°C meets your environmental requirements. Cross-reference the 1700-2700 MHz frequency range against your system's center frequency to ensure adequate performance margins.

Selection Notes

Select this component when a miniature transformer is required for the 1.7 to 2.7 GHz band. The 1:1 ratio makes it suitable for impedance matching between balanced and unbalanced circuits without gain or loss transformation. Consider the LTCC construction for stability in high-frequency environments. Evaluate the thermal performance at the upper limit of 125°C if operating in harsh conditions.

Part Context

This part belongs to Mini-Circuits' portfolio of RF transformers and baluns. It complements other components like the SCG series splitters by providing necessary signal balancing functions. The TCW1-272+ serves as a passive linear component essential for maintaining signal integrity in modern wireless infrastructure and consumer electronics designs requiring small form factors.

Replacement Considerations

Direct substitutes include other 1:1 LTCC transformers covering the 1700-2700 MHz range with identical 50 Ohm impedance and JC0603C footprints. Verify pinout compatibility and insertion loss specifications before swapping manufacturers.
