Frequencies and bandwidths once thought “impractical” or at least “for the military,” at millimeter-wave (mmWave) frequencies, are rapidly becoming more commercially commonplace. Two strong examples are in Fifth Generation New Radio (5G NR) wireless networks and 77 GHz automotive radars, where mmWave frequencies are channeled through highly integrated printed circuit boards (PCBs). The PCBs are often in multilayer configurations that handle different types of signals, including analog, digital, RF and mmWave signals. Modern circuit designers are faced with integration and miniaturization, trying to pack as many functions into the smallest PCB possible. But different circuit functions have different circuit material requirements, and circuit materials that provide optimum performance at mmWave frequencies may not be the most practical solution for power supply circuitry.
