Investigation of microwave properties of planar heterojunction diodes in Ka frequency range using probe station

Usual method to investigate high frequency parameters of the microwave diodes is to mount the single diode into microwave transmission line with following measurements of the detected voltage, for example. However, this is a time consumable process. Time savings can be achieved using RF probes for the detection measurements. We present investigation of detection of microwaves signals using heterojunction planar microwave diodes array on polyimide film when the microwave signal is fed to the diode through coaxial line.
