InP HEMT for sub-millimeter wave space applications: Status and challenges

InP HEMT technology has long had a place in both civil and defense space applications, particularly at millimeter wavelengths where it´s high speed and low DC power provide clear benefits. With a new generation of transistor showing f_MAX > 1.2 and integrated circuits operating frequencies reaching 850 GHz, new performance levels and applications become possible. This talk will provide a status of capabilities and technology readiness, as well as emerging applications.
