Product Description

Taconic RF-35TC High Frequency PCB 20mil 0.508mm RF-35TC RF Circuit Board with Black Solder Mask and Immersion Gold
(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.
