TRF-45 High Frequency PCB Solutions for Advanced RF Applications

September 20, 2025

As wireless and high-frequency technologies continue to advance, the demand for reliable, low-loss PCB materials has never been greater. Among the top-tier options available today is TRF-45, a high-performance laminate developed with Taconic’s advanced ceramic expertise.

Whether you're designing satellite communication systems, RFID tags, or GPS antennas, TRF-45 offers the electrical and mechanical properties needed to ensure signal integrity and long-term reliability.

What Is TRF-45?

TRF-45 is a high-frequency circuit board material reinforced with woven glass, offering exceptional dimensional stability and thermal performance. A key advantage of TRF-45 lies in its controlled Z-axis expansion, which remains stable across a broad temperature range — even during soldering processes.

What’s more, TRF-45 is fully compatible with standard PCB fabrication techniques, including shearing, drilling, milling, and plating, making it as practical as it is powerful.
