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. Mason, "Power Gain in Feedback Amplifiers",Transactions of the IRE Professional Group on Circuit Theory, Volume CT-1, Issue 2, June 1954, pp. 20-25.

WebTo enable CMOS-compatible GaN HEMTs for the next generation of communication systems (5G and beyond), a low gate resistance is of great importance since it directly affects the RF power gain and fMAX of the transistor. In this article, the impact of various gate-metal stacks on the gate resistance and RF performance of the devices is studied. WebField 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. L g =100 nm devices show DC drain current I D =600 mA/mm (V GS =-3V, V DS =-10V) with transconductance g m =140mS/mm (V GS =-0.3V, V DS =-4V).
