The Taconic TSM-29 PCB is a high-performance, low-loss RF substrate engineered specifically for demanding microwave and millimeter-wave circuitry. Designed for hardware engineers and product developers working in high-frequency environments, this material delivers a predictable dielectric constant ($D_k$) of 2.9 alongside an exceptionally low dissipation factor. This ensures minimal signal attenuation and optimal impedance control across broad frequency bands, making it an ideal foundation for complex RF front-ends and antenna systems.

Key Features of Taconic TSM-29 Substrates

• Dielectric Constant ($D_k$): Stable 2.9 at X-band frequencies for precise impedance matching.

• Low Dissipation Factor ($D_f$): 0.0017 at 10 GHz, ensuring minimal insertion loss in critical signal paths.

• Thermal Conductivity: High thermal performance ($0.56\text{ W/m}\cdot\text{K}$) to manage localized heat dissipation efficiently.

• Dimensional Stability: Exceptionally low X, Y, and Z-axis thermal expansion coefficients (CTE) preventing trace delamination.

• Moisture Absorption: Less than 0.02% absorption rate, maintaining electrical performance in humid environments.

High-Frequency Applications

• Aerospace & Defence: Radar systems, satellite communications, and guidance arrays.

• Telecommunications: 5G base stations, power amplifiers, and low-noise amplifiers (LNAs).

• Automotive: Advanced driver-assistance systems (ADAS) and 77 GHz radar modules.

• Industrial Wireless: High-speed data links and automated test equipment (ATE).
