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. WebNos transistors ont donné une fréquence de coupure maximale ft de 43 GHz et une fréquence d'oscillation maximale fmax de 23 GHz ouvrant la possibilité de réaliser un circuit amplificateur allant jusqu'à 10 GHz. Fmax is the frequency where unilateral gain (U) becomes unity, or zero dB. "U" was developed by Samuel Jefferson Mason, (and also known as Mason's Invariant", the concept was published when transistors were having their third birthday party (reference at end of page). It is still one of the most important … See more We'll add to this later. FT is the "transition frequency" where current gain goes to unity (zero dB). See more S.
