5-55 GHz Watt-level Gallium Nitride Stacked FET Travelling-Wave Power Amplifier

Two well-known ultra wide-band topologies, the travelling-wave amplifier and the stacked cell, are gainfully employed to demonstrate a decade bandwidth behaviour (5-55 GHz) in conjunction with watt-level saturated output power. The selected technology is OMMIC’s Gallium Nitride on Silicon, featuring the possibility to simultaneously insert 60-nm and 100-nm gate length FETs in the same MMIC.
