ABSTRACT:
Disclosed is a dielectric image guide integrated circuit including first and second sections of image guide of preselected cross-sectional areas joined by an image guide transition section of variable cross-sectional area and all mounted on the surface of an image or ground plane. The image guide transition section has a cavity therein for receiving microwave/millimeter wave energy from the first section of the image guide, and this energy is coupled into a diode mounted within the cavity where it is either detected or frequency converted by the diode. Advantageously, the diode may be mounted on a metal cover which is positioned atop the cavity in the waveguide transition section, and it receives its operating bias from a bias pin connection extending through an opening in the ground plane and including a wisker contact to the diode.
