Abstract :
The RF cryogenic performance of ultra-low-loss, wideband (DC to 40 GHz) single-pole double-throw (SPDT) RF switches implemented in a 180 nm SOI CMOS technology is reported for the first time. Results show that the switch insertion loss (IL), isolation (ISO), small- and large-signal linearity all improve as the temperature decreases. DC characterization of individual transistors was performed and analyzed to provide insight into the mechanisms underlying the observed changes in the RF switches.
