Domain-Decomposition Harmonic Balance with Block-Wise Constant Spectrum

Domain-decomposition techniques provide a powerful approach to the circuit-level simulation of complex RF/microwave transceivers by envelope-oriented harmonic balance. Once the circuit has been suitably subdivided into blocks, a further significant enhancement in analysis performance may be obtained by limiting each block´s spectrum to the set of lines that are relevant to the block electrical function. Besides providing high numerical efficiency, this technique opens the way to an effective co-simulation of the RF and baseband transceiver sections
