The active components (phase shifters, LNAs) of a Ku-band direct radiating array are a major part of its cost. A way to reduce this cost is to use simpler control elements. In the frame of ESA project ...

Abstract: 3D stacked devices have been developed and manufactured to realize gains in power, performance, area and cost (PPAC) in various devices. In this work, CMOS directly bonded to array (CBA) ...
