We explore large-signal network analysis for the over-the-air test of up-converting and down-converting phased arrays. The approach first uses a vector network analyzer to calibrate the impulse response of an over-the-air test system at RF. The vector network analyzer is then power- and phase-calibrated and utilized with the over-the-air test system for the measurement of up-converting and down-converting phased arrays with an IF input or output. We illustrate the approach with measurements of a down-converting phased array.
