RF-35TC is a high - frequency material developed by Taconic company. It stands out with its "best in class" low dissipation factor combined with high thermal conductivity. This makes it the perfect choice for high - power applications where even the slightest difference of 1/10th of a dB can be crucial. In such applications, the PCB substrate, like RF - 35TC, is expected to efficiently dissipate heat away from both transmission lines and surface - mount components such as transistors.
RF-35TC is a PTFE - based, ceramic - filled fiberglass substrate. One of its significant advantages is its stability. Unlike its synthetic rubber (hydrocarbon) competitors, RF - 35TC will not oxidize, turn yellow, or experience an upward drift in dielectric constant and dissipation factor. This stability ensures consistent performance over time.
This laminate features a low dielectric constant value of 3.50 and an extremely low Df of 0.0011. These characteristics result in a low dissipation factor. Coupled with its high thermal conductivity, RF - 35TC also bonds very well to low - profile copper. This excellent bonding ability further reduces insertion loss, enhancing the overall performance of the circuits.
The RF - 35TC laminates are highly suitable for a range of applications, including antennas, satellites, filters, couplers, and power amplifiers. Their unique properties make them an optimal choice for these high - frequency and high - performance applications. |
