The paper deals with the numerical simulation of Gunn diodes operation based
on the graded-gap AlInN. We have obtained the output characteristics of diodes with
different cathode contacts in a wide range of frequencies. Harmonic and biharmonic
modes of operation have been considered. Cutoff frequency and minimum length of the
active region have been estimated. Performances of graded-gap AlInN diodes are
compared with the performances of InN and AlN diodes
