THE RAPIDLY DEVELOPING monolithic GaAs technology is expected t o have a major impact on radar and communications systems. Specifically, high volume production offers thc possibility of achieving low cost receivers and transmitters. This paper will describe the fabrication technology of monolithic heterodyne receivers for millimetcr-wave frequencies.Two types of receiver designs available for monolithic integration are the linear amplifier front end and mixer-IF amplifier front end. At microwave frequencies (…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
