An approach to millimeter-wave integrated circuits was studied in which silicon dielectric waveguides are used as transmission lines. Compatible devices and components can be built into the line or attached to the line in such a manner that generation, control, and processing of the signal can be carried out by conductivity modulation techniques. Experiments were carried out demonstrating that mechanical phase shifters and tuning elements, based on this principle, can provide as much as 250 degreescm phase shift. Electronic phase shifters were demonstrated with 90 degreescm and little or no change in attenuation. Oscillators were constructed in semiconductor dielectric cavities for the first time with unloaded and loaded quality factors competitive with metal waveguides.
