We have developed a 60-GHz-band ultracompact transmitter for short-range transmission of High Definition TV (HDTV) program material. This transmitter utilizes microwave direct-frequency modulators with simplified temperaturecompensation circuits and millimeter-wave modules involving MMIC multipliers and power amplifiers incorporated with integrated planar antennas. This structure has enabled the development of a pocketsized transmitter ( 120 x 90 x 30 mm') with a low power consumption of 2.2 W. With this transmitter, HDTV signals have been successfully transmitted on an experimental video link with this transmitter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
