Abstract

The rapid growth in mobile users andhigh-bandwidth applications is creating unprecedented challenges andopportunities in telecommunications. As we address the need for higher datarates, the mm-Wave 5G bands have been expanded to accommodate this demand. With6G on the horizon, targets are aiming for a 1 Tbps peak data rate,necessitating the allocation of even wider bands in the mm-Wave and sub-THzfrequencies. Directive communications using affordable phased arrays have beenadopted as a key technology for building mm-Wave communication systems toovercome the large free space path loss.

This talk will address the challengesassociated with designing mm-Wave ultra-wideband integrated circuits andphased-array systems capable of operating over a widespread spectrum usingadvanced SiGe technology. Additionally, a recently introduced 64-elementwideband scalable phased array design will be showcased, with a demonstrationof the 20-50 GHz multi-band operation. The talk will conclude with the keyopportunities and future directions in phased-array systems design.
