Complete Teardown Report of Qualcomm's 60GHz WiGig/WiFi 802.11ad Chipset -


The "Qualcomm
60GHz WiGig/WiFi 802.11ad Chipset World's First Smartphone Edition
Complete Teardown Report"
report has been added to's

This report includes a full investigation of the system, featuring a
detailed study of the SiPs and the antenna board including die analyses,
processes and board cross-sections. It contains a complete cost analysis
and a selling price estimation of the system. Finally, it features an
exhaustive comparison with the Qualcomm QCA9500, which is dedicated to
routers or mobile computers.

2018 is a turning point for 5G communications. All players have done
several studies on huge data rates using millimeter wave (mmWave)
compared to current technologies. Today, manufacturers are focusing on
backhaul applications with high power and no voltage limitation. But the
next steps - such as handset applications - are gaining attention as
integration will have several issues to solve, including chip
implementation, packaging technology, antennae placement and heat
management. Using the 60GHz band, the IEEE has licensed a Wi-Fi 802.11
protocol, known as WiGig. Today, a few routers and only one commercially
available smartphone use this protocol, providing an early glimpse of 5G
mobile capability and using Qualcomm's chipset.

This complete solution has been designed for smartphones, especially for
ASUS. The module, integrated in the ASUS ZenFone 4 Pro, comes with two
systems linked by a coaxial connection. Both Systems-in-Packages (SiPs)
use non-conventional double-sided molded packaging developed by Murata.
One is integrated on the main board and the other features innovative
antennae integrated into an organic PCB. The latter SiP integrates
almost 20 antennae, a radio frequency integrated circuit (RFIC) die,
thermal management and isolation solution, all in a single package
smaller than 40mm.

Developed by Wilocity, which has been a Qualcomm subsidiary since 2014,
the RFIC features up to four transceivers controlling up to 32 antennas,
both patch and dipole, for beamforming at 60GHz. Both SiPs have very
thin confined PCB substrates and embedded copper pillars realizing the
signal distribution structure. This first integration of such a mmWave
device in a handset shows the full compatibility of this SiP technology
that could answer 5G integration issues.
