We report state‐of‐the‐art measured performance of class‐B dual‐gate GaAs power FETs fabricated using a highly manufacturable SAG technology. The class‐B devices use selective co‐implantation for FET channel formation and demonstrate 640 mW / mm (for 2.5 mm FETs) of power at C‐band with 45% PAE and 11.4‐dB gain.
