The development status of millimeter-wave HEMTs on GaAs has improved to a status where widespread use has become normal in modern information system for communication and sensor application. The remaining challenge for MMICs is to meet the cost margin in order to be economically attractive for commercial markets. For commercial applications it is generally preferred to offer performance identical to competing technologies at a lower cost than to offer improved performance a the same cost. Although it seems enigmatic, for certain rapidly evolving system applications, alternative InP-based generations of HEMT devices either on InP- or GaAs-substrate may become attractive. This paper focuses on this topic.
