Helicopter rotating hub mounted vibration control system for a rotary wing hub having periodic vibrations while rotating at an operational rotation frequency. A set of individually defined random values is used to mask each entry in a substitution table, defining a masked substitution table. The outphasing modulator may also include a sum-difference combiner to produce outphased modulated signals from the phase shifted modulated signals. Metal wirings connecting to the through electrodes are formed on the insulating layer. The second region is provided at a scribe line of the semiconductor substrate.
