A solid-state regenerative repeater for guided millimeter-wave communication systems

Recent advances in solid-state device technology for generating millimeter waves as well as advances in component design for IF and baseband portions of repeaters have renewed interest in millimeter-wave guided-wave communication systems. This paper describes a 306 Mb/s, all solid-state repeater which has been built using a 1.3-GHz IF and a form of differentially-coherent phase modulation. A signal-to-noise ratio of 13.6 dB is required for an error probability of 10−9 (compared with a theoretical value of 13.0 dB for an ideal differentially-coherent phase-modulated system). Sufficient gain for 15-mile repeater spacings (using two-inch circular waveguide) has been obtained with an LSA diode, an IMPATT diode, and a varactor multiplier as the millimeter-wave power source.
