ABSTRACT:
The specification describes a dielectric image guide harmonic pumped mixer circuit wherein two dielectric image guide strips of different chosen cross-sectional configurations are mounted on a metallic substrate which forms the image plane for the mixer circuit. These image guide strips have impedance matching tapered ends which extend into a central mixer cavity region on the substrate. A pair of reverse poled mixer diodes are mounted in the central cavity region to receive respectively RF incoming signals from one dielectric image guide and local oscillator signals from the other dielectric image guide. Differential currents generated in the two diodes cause the second harmonic of the local oscillator signal frequency to mix with the incoming RF signal frequency. An intermediate frequency (IF) signal current produced thereby is conductively coupled from the mixer cavity into IF signal processing electronics.
Advantageously, the image plane substrate surface is configured to receive, in a coplanar fashion, a modular circuit board containing electronics such as an IF amplifier, mixer, and detector which in turn are conductively coupled to the mixer diodes by a metallic strip or the like in a compact, substantially planar-upper surface configuration.
