Towards over the air characterized transmitter array nonlinearity

Millimeter-wave (mmW) phased arrays challenge the standard ways to measure and specify the nonlinearity of the radio frequency transmitter. Furthermore, the linearization of these multi-antenna transmitters is challenging due to the single digital input shared by multiple nonlinear elements. The figures of merit of linearity of mmW phased array transmitter must be measured in the radiated far-field and the array linearization must be designed for the signal observed over-the-air.
