Beamforming and MIMO Transceivers for Communication and Radar Systems

Beamforming and spatial-filtering in multi-beam and MIMO arrays are a key part of emerging wireless communication networks and sensing paradigms. This talk will focus on beamforming/spatial-filtering architectures and circuits for integrated mm-wave transmitter and receiver arrays targeting multi-Gb/s communication and high-resolution radar systems. Design strategies for analog/digital-intensive building blocks specific to integrated-arrays, such as phase shifters and signal combiners, will be discussed in the context of array system performance and link budget. An overview of transmit/receive circuit/system challenges in large-scale arrays will be presented followed by approaches towards realizing scalable, digital-intensive large-scale arrays.
