A Scalable Heterogeneous AiP Module for a 256-Element 5G Phased Array

Abstract

This talk discusses design and integration considerations of a scalable 24–30GHz 256-element phased array antenna module consisting of four 64-element tiles. This phased array module employs a heterogeneous integration approach to enable the effective and efficient integration of multiple ICs, bandpass filters, splitters, combiners, and decoupling capacitors in a multi-layered organic substrate which also integrates the 64 dual-polarized antenna array. This talk also introduces and addresses technical challenges that arise in the heterogeneous integration of such large mm-wave antenna-in-package (AiP) designs.
