Silicon-on-Insulator, namely GlobalFOundries 22FDX and 45RFSOI (now 45RFE) with their very high ft and fmax, low power operation and back-gate biasing in 22FDX, and most important, extremely low noise figure and high efficiency power amplifiers, have been shown to be the ideal processes for microwave and mm-wave applications such as SATCOM, 5G and 6G. The talk will present some of the record circuits and systems built using these processes and how they are changing SATCOM and making 5G/6G possible.
