Abstract:
For millimeter wave (mmWave) applications, a novel methodology with intelligent regulation of ultra-wideband (UWB) subassembly based on multi-chip module (MCM) opens a distinct perspective. First of all, the nonnegligible essentiality of gain flatness in high-integrated mmWave transceiver is proposed and theoretically demonstrated, and in view of this, the unsophisticated scenario is investigated utilizing active amplifier and passive attenuator, whilst the intelligent regulation utilizing other active and passive components is homologous, respectively. Secondly, we examine the model of electromagnetic (EM) field simulation by constructing three-dimensional (3D) configuration in computer simulation technology (CST) software, and in the meantime, encoding the equidistant points of coordinates on the microstrip lines, we implement the matching blocks regulated intelligently and optimized iteratively in the afore-mentioned models of 3D EM field simulation and field-circuit co-simulation utilizing s-parameters derived from components, gold wires and simulated printed circuit board (PCB) in advanced design system (ADS) tool. Subsequently, other characterizations of matching blocks can be simulated and iterated correspondingly to optimize the gain flatness, respectively. Furthermore, we explore the optimized case to fabricate prototype, whilst verifying two mmWave connectors. Eventually, the UWB subassembly is assembled and fabricated with the magnitude of 47 mm × 30 mm × 10 mm and the weight of 26 g. More interestingly, the curves of field-circuit co-simulation are in excellent accordance with experiments, which proves the unique effectiveness of the proposed intelligent regulation for mmWave applications. Moreover, the multifunctional subassembly can be also utilized to validate the impact of the blocking capacitors and mmWave connectors on the gain flatness with important practical value. Incorporating software and hardware, the novel methodology connects the digital w...
