This paper proposes a method to measure the in-band deterministic and stochastic contributions of nonlinear distortions and mixers. The model of the mixer as a two- or three-port device is developed. Based on this model, the measurement technique—which is a generalization of the methods developed for amplifiers—is developed. While designing the measurement method, the difficulties that arise out of the fundamental differences between mixers (three-port devices) and amplifiers (two-port devices) are taken into account. Two techniques are presented, depending on the fact that the phase of the local oscillator is known or unknown.
