Thermally conductive low loss laminate

RF-35TC 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 PWB substrate is expected to diffuse heat away from both transmission lines and surface mount components such as transistors or capacitors. 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.|The low Z axis CTE and temperature stable Dk are critical for both narrow band and broad band overlay couplers. The low X and Y CTE values are crucial for maintaining critical distances between trace elements in a printed filter. The extremely low Df of 0.0011 and high thermal conductivity are particularly suited for power amplifier applications.
