Frequency converters and mixers used in RF, microwave and mm-wave applications are often characterized for their magnitude, phase and group-delay performance. One method, the “SMC+Phase” method, ...

In this paper, a 3D beamforming phased array with 2D stacked tunable Nolen matrix is presented. The fundamental building block - tunable Nolen matrix is proposed to relax phase tuning range of phased ...
