High-Q waveguide resonators have become more commonplace since the losses of planar circuit are significant at higher frequencies. In amplifiers design, three-dimensional (3D) waveguide cavities are often employed as the matching networks of the planar circuits including the transistor. Thus, the interconnection of the waveguide-to-microstrip transition and the feedback of the transistor itself make the calculation and optimization of the physical model more difficult. The neural network technique can be used in the electromagnetic (EM) optimization of the waveguide amplifiers, leading to improved design efficiency.
