The paper shows a circuit-level/electromagnetic co-simulation tool for the rigorous analysis of time-modulated arrays in presence of digitally modulated carriers. The Harmonic Balance (HB) technique is used for the accurate description of the nonlinearities, and is combined to the full-wave description of the radiating array. The resulting large dimension of the solving system is efficiently managed by the further deployment of a model-order reduction HB technique. The developed tool overcomes simplifying assumptions of previous approaches and its effectiveness is verified with numerical examples in both modulated and unmodulated carrier cases.
