Abstract
This paper presents a multi-standard fully con-
nected hybrid beamforming (FC-HBF) receiver that can be
reconfigured between two fully connected two-stream multi-
input-multi-output (MIMO) modes at 28- or 37-GHz band,
and an inter-band carrier-aggregation (CA) mode enabling
concurrent single-stream operation at 28 and 37 GHz. A new
image-reject (IR) heterodyne beamforming architecture is intro-
duced that facilitates easy reconfiguration. Concurrent dual-band
operation of the beamformer front end
