Modelling of millimeter wave two terminal devices and related circuits

International audienceThe authors describe a self-consistent modeling of millimeter-wave diodes (GUNN, IMPATT, and p-i-n) for applications such as power sources or limiters. Particular emphasis is placed on temperature rise within the devices to achieve reliable high-power operation. Circuit loading is also considered for a more realistic description of the operating mode. The proposed CAD (computer-aided design) technique has proved to be an efficient tool leading to the design and realization of high-power high-efficiency W-band sources operating at safe temperature ris
