Abstract
A phased array includes a number of transmission units with an unequal array of power amplifiers for receiving or transmitting input signals at millimeter wave frequencies. The phase array transmits millimeter waves in air to reconstruct original phase-and amplitude signals by combining the signals from the unequal array of power amplifiers. The unequal array of power amplifiers comprises power amplifiers having a higher peak power than other power amplifiers of the array. The power amplifiers can also have different transmission powers from one another.
