Introduction to RF-35TC
RF-35TC is a high-frequency material developed by Taconic. This substrate boasts a "best-in-class" low dissipation factor and exceptional thermal conductivity, making it ideal for high-power applications where every 1/10th of a dB is crucial. The PCB substrate effectively dissipates heat from both transmission lines and surface mount components, such as transistors.
Material Composition
RF-35TC is constructed from a PTFE-based, ceramic-filled fiberglass substrate. Unlike synthetic rubber (hydrocarbon) alternatives, it does not oxidize, yellow, or experience upward drift in dielectric constant and dissipation factor.
With a low dielectric constant of 3.50 and an extremely low dissipation factor of 0.0011, this laminate ensures minimal energy loss. It also bonds exceptionally well to low-profile copper, further reducing insertion loss.
RF-35TC laminates are perfectly suited for a variety of applications, including antennas, satellites, filters, couplers, and power amplifiers.
