By utilizing gate-line capacitive division and low-loss coplanar waveguides, the fabricated TWA exhibits 7.4dB gain with a 3dB bandwidth of 80GHz while maintaining input and output return losses better than 8dB from dc to 100GHz. A GBW of 190GHz is achieved.[SDGs]SDG7conference paper10.1109/isscc.2005.14939152-s2.0-28144461122
