High Thermal Conductivity Laminate


View Product 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.
