GaN on SiC: The Optimal Solution for 5G | Wolfspeed

While silicon has high resistivity at room temperature, wireless infrastructure generally operates “hot.” At high temperatures, silicon is conductive, and RF coupling to the substrate can occur. When it is cooled, the GaN will shrink more than the silicon substrate. With this, some RF power to the substrate is lost, decreasing efficiency.
