RF PCB Toolbox™ provides metal and dielectric material libraries. You can use different types of materials to create printed circuit board (PCB) components. Use this category to select PCB component materials with considerations to properties such as electromagnetic losses, mechanical strength, and thermal properties. The values of the dissipation factor and dielectric constant are important when considering electric losses. Electric losses are directly related to insertion and transmission losses in a PCB. Higher values of electrical losses result in performance degradation of PCBs like less radiated power, broadening of return loss resonance, thermal effects at high power levels and many more.
