ABSTRACT:
A millimeter wave integrated oscillator circuit utilizing an active device uch as an IMPATT or Gunn diode device located in a metallized dielectric cavity which is an extension of a half-height rectangular cross-sectional boron nitride image guide having a metallized under surface solder bonded to a metallic substrate forming an image plane. The diode is energized by means of a bias conductor fed into the cavity through a small slot in the cavity wall. One end of the image guide terminates in the cavity, while the opposite end is tapered along its sides and terminates in a full height hollow metal waveguide section partially including the metallic substrate. The metal waveguide section, moreover, includes flanges for coupling external circuit means to the image guide to metal waveguide transition.
