Abstract :
We present the state of the art of microwave performances of silicon heterostructures FETs (hetero-FETs). Recent advances
are illustrated on using DaimlerChrysler (DC) technologies. fMAX as high as 188 and 135 GHz with minimum noise figure,
NFmin as low as 0.3 and 0.5 dB at 2.5 GHz are reported, respectively, for n- and p-MODFETwith gatelength from 100 to 130 nm.
Experimental data and physical simulations of optimized structures show that fMAX of 70 nm gatelength n-MODFET could
reach 360 GHz.
