TL;DR: The RFIC reported here supports concurrent and independent dual-polarized operation in TX and RX modes, and is compatible with a volume-efficient, scaled, antenna-in-package array.
Journal ArticleDOI
A voltage-mode RF DAC for massive MIMO system-on-chip digital transmitters
TL;DR: A novel radio frequency digital-to-analog converter (RF DAC) solution is presented, that is also capable of monolithic integration into today’s digital ASIC due to its digital-in-nature architecture, and shows excellent linearity performance for output frequencies up to 10 GHz.
Journal ArticleDOI
Direct digital-to-RF converter employing semi-digital FIR voltage-mode RF DAC
TL;DR: A direct digital-to-RF converter (DRFC) is presented in this work, which benefits from technology scaling and can be monolithically integrated into advance dSPs.
