Taconic High Frequency PCB Built on RF-35TC
10mil 0.254mm with Immersion Gold for Filters and Couplers etc.
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.
