Fmax of transistor

WebDiamond RF Transistor Technology with f t =41 GHz and fmax=44 GHz Abstract: Initial results for diamond RF transistor technology are presented. Field Effect Transistors (FETs) were fabricated with gate lengths (L g) ranging from 4μm to 50nm. The FETs have total gate width (W g) of 40 or 120μm. Webf max depends up on the parasitic components present in the equivalent circuit of a transistor in addition to the intrinsic components. How can we predict that whether f max is larger than f T or...
