RF-35HTC High Thermal Conductivity Laminate technical data sheet
●RF-35HTC is a non-reinforced, low loss, industry leading thermally conductive laminate. The high 1.84 watts/M*K thermal conductivity is well suited for any high-power application including amplifiers, couplers, dividers, filters etc. RF-35HTC is a ceramic/PTFE composite that is very low in PTFE content. The extremely low loss of 0.0007 at 10 GHz makes RF-35HTC very attractive for any high-power application.
●The high thermal conductivity is beneficial for moving localized heat away from transistors, capacitors, conductors, other components, or the dielectric material. In hot environments exposed to oxygen, hydrocarbon (synthetic rubber) based composites are prone to oxidation and higher than expected electrical/thermal losses predicted from modeling. PTFE is attractive at the highest of temperatures because PTFE resists any thermal oxidation.
●Uniform distribution of ceramic in the dielectric ensures a uniform dielectric in the X, Y, and Z directions. The low X and Y CTE ensures good performance of filters over temperature. The low Z axis expansion ensures stable performance of narrow band or broad band couplers over temperature and stable signal to ground plane dielectric thickness (stable impedance) over temperature. The low PTFE content of RF-35HTC facilitates plating and drilling in printed circuit board fabrication. The high concentration of ceramic contributes to improved dimensional stability. Taconic has avoided the use of alumina that is abrasive to mechanical drilling or routing.
●Power handling experiments were conducted on microstrip transmission lines with and without various capacitors at the center of the microstrip to quantify the capability of the dielectric to spread thermal energy. The heat profile of the microstrip, both with and without a capacitor, and any hot spots was captured using a thermal camera. Transmitted power was increased to 200 Watts. Taconic’s RF-35HTC was compared to Taconic’s RF-35TC and RF-35TC-A, as well as to two available competitive materials. In every case, the RF-35HTC dielectric material outperformed all other materials in its ability to spread thermal energy, as shown on page 2.
●RF-35HTC is compatible with all Taconic 1 oz copper with ULP 1 oz copper being recommended at high frequencies for the lowest insertion losses.
