AI capabilities are pushing more RF flexibility and better devices to the
antenna interface with the physical world. Adaptive MIMO transmitter and receiver
arrays will be core components in integrated communications and sensing for
future wireless applications. Using large-scale transmit and receive arrays at 140
GHz, we have pushed CMOS circuit architectures that leverage digital modulation
at the antenna array to support energy efficient radar and high-speed data
communication. PseudolithIC is developing heterogeneous integration for the
high-frequency electronic markets can place compound semiconductors into
antenna arrays for low-cost, high- performance circuits. The combination of digital
techniques and more powerful RF devices promises autonomy in RF integrated
circuits to react to the spectrum around the antenna.
