The R/F7 transistorized 6-gigacycle microwave system

Greater dependence of the United States on telecommunications has increased the demand for higher reliability and transmission quality on communication systems, and information capacity requirements on microwave relay systems has increased almost exponentially in the past few years. The advent of semiconductors with subsequent improvement in life and frequency range has made possible new microwave equipment which is reliable, compact, economical, and which provides high information capacity and high-quality transmission. This paper discusses the design of the transistorized RF/7 microwave relay system which was first placed in service during 1961.
