  • Abstract
    An In0.52Al0.48As/n+-In0.53Ga0.47As MIS-type field-effect transistor (FET) with a channel doped at a 7 × 1017cm-3level has been fabricated on an InP substrate. A device with a 2-µm channel length has yielded a maximum transconductance of 152 mS/mm, f_{T} = 12.4 GHz, and f_{\\max } = 50 GHz. At 10 GHz, the maximum available gain is 17.4 dB. The performance of this device shows that heavily doped channel FET\´s are very promising for high-frequency operation.
