    Is it because HEMT usually using in Radio frequency?

    RF device modeling looks at the behavior of devices across a range of frequencies. Things like input impedance, output impedance, and gain change as a function of frequency.

    An HEMT is designed to operate at frequencies of 100's of GHz to a THz. At these frequencies inductors look like open circuits and capacitors look like dead shorts.
