Look up: thousands of satellites are streaming broadband from low Earth orbit. Look around: radars that once rotated on masts now steer their beams electronically without moving the antenna, and 5G repeaters are pushing mmWave coverage further than ever. Behind each of these breakthroughs is the same quiet revolution in the RF signal chain, and the same relentless pressure to deliver more performance in less size, weight, power and cost. In this fast-paced session, we pull back the curtain on how today's most demanding RF systems are built. You'll discover how beamforming really works, and why a handful of low-cost diodes can now steer a beam that once required an expensive active array. You'll see why GaN-on-SiC has taken over high-power transmitters while GaAs still rules the quiet world of low-noise receivers, and how engineers keep signals clean in an ever more crowded spectrum. From radar front ends and kilowatt-class avionics transmitters to components that must survive the radiation of space, we'll follow the signal end to end, finishing with the innovations that are shrinking entire filter banks onto a single part and pushing oscillator phase noise to new lows. Bring your toughest questions for the live Q&A.
