The phase error distribution caused by the selection of the working point and synchronization characteristics of an array of mutually coupled harmonic self-oscillating mixers (HSOMs) in a receiving topology is studied using simplified models and a nonlinear analysis. The influence in the phase error of the synchronization phase and the mismatches between the free-running and synchronization frequencies are studied separately. A 4 × 1 element array based on injection-locked and mutually coupled HSOMs has been manufactured for the experimental validation of the simulated results.
