  • Abstract
    A W-band (75-110 GHz) wafer probe is presented. The probe uses ridge-trough waveguide to transition from a rectangular waveguide input to coplanar waveguide used on the probe board output. Research was conducted on radiation loss and moding in coplanar waveguide to minimize insertion loss and maintain a coplanar mode. The probe is shown to work successfully and data is presented for W-band HEMTs.
