Taconic High Frequency PCB Built on RF-35TC 60mil 1.524mm With Immersion Gold for Satellites
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
RF-35TC is a type of high frequency material from Taconic company. It offers a "best in class" low dissipation factor with high thermal conductivity. This material is best suited for high power applications where every 1/10th of a dB is critical and the PCB substrate is expected to diffuse heat away from both transmission lines and surface mount components such as transistors.
RF-35TC is a PTFE based, ceramic filled fiberglass substrate. It will not oxidize, yellow or show upward drift in dielectric constant and dissipation factor like its synthetic rubber (hydrocarbon) competitors.
This laminate has a low dielectric constant value of 3.50 and has extremely low Df of 0.0011. It provides a low dissipation factor with high thermal conductivity and bonds very well to low profile copper, further reducing insertion loss.
The RF-35TC laminates are ideal for antennas, satellites, filters, couplers and power amplifiers.
