A novel uniplanar bi-phase (0/spl deg/-180/spl deg/) modulator/mixer

The overall goal of this paper is to design a new modulator/mixer at 38 GHz in uniplanar technology. The primary objective is to develop a theoretical and an experimental study of each elementary block in the millimeter frequency range, allowing us directly to design the device at 38 GHz. As part of this study, a uniplanar modulator/mixer was built in X band in order to aid in the verification of the design concept.
