Abstract

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 temperature-compensation circuits and millimeter-wave modules involving MMIC multipliers and power amplifiers incorporated with integrated planar antennas. This structure has enabled the development of a pocket-sized transmitter (120/spl times/90/spl times/30 mm/sup 3/) 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.
