Abstract

Disclosed are integration approaches for mm-wave planar phased array type architectures using multilayer substrate technologies. For instance, an apparatus may include a plurality of substrate layers, an integrated circuit, and a connector module. The plurality of substrate layers includes a first substrate layer having one or more phased array elements. The integrated circuit exchange one or more radio frequency (RF) signals (e.g., mm-wave signals) with the one or more phased array elements. The connector module exchange further signals with the integrated circuit that correspond to the one or more RF signals. For example, these further signals may be baseband or intermediate frequency (IF) signals.
