  • Abstract
    Summary form only given, as follows. In this paper, the design of a broadband fundamental mixer using an improved Lange coupler is presented. This W-band image reject mixer is implemented in 0.15-µm GaAs PHEMT process. This mixer demonstrates measured conversion loss about 10.5 dB from 90 to 112 GHz and image rejection about 15.9 dB from 82 to 116.5 GHz. All the characteristics of this mixer facilitate the application in ALMA project.
