Abstract :
A W-band wafer probe based on a coaxial line design has been developed. With built-in bias tee, 2-dB insertion loss and better than 12-dB return loss from 75 GHz to 110 GHz are achieved. A probe without bias tee has 1.3-dB loss and 1.5-dB return loss at 94 GHz when optimized for narrowband application. S-parameters of discrete transistors and circuits have been accurately measured from 75 GHz to 110 GHz. The noise figure of active circuits has also been measured at W-band with these probes.<>
