Research on Integrated Near-Millimeter-Wave Receiver,
Abstract
This report deals with problems in the design of monolithic millimeter-wave circuits. Emphasis is placed on: (A) design of dielectric ridge waveguides for millimeter-wave integrated circuits, and (b) a monolithic Schottky diode imaging array at 69 GHz. The general problem of the design of a specific all-dielectric waveguide, the dielectric ridge guide is considered. A planar metallic V-coupler is designed to couple energy efficiently between the waveguide and lumped circuit elements. The principal method used is simulation in the range of 2-7 GHz. With good compromise design, typical coupling loss between waveguide and a small device is about 1.4 dB, exclusive of dielectric loss and ohmic loss in the computer. The use of dielectric ridge guide is attractive especially at the higher end of the millimeter-wave spectrum where metallic loss is excessive. Monolithic Schottky diode imaging arrays with integral antennas have been built and tested at 69 Ghz. An immersion-lens optical system is used for imaging. The measured video responsivity is 534 V/W, from which an optical coupling loss of 7 dB is deduced.
