    This article discusses millimeter-wave Gigabit-class radio systems operating at 1-10-Gb data rates, i.e., at fiberoptic speeds. Yet, we need to talk first about fiber optics. There has been stunning progress in high-speed fiber optic technology during the past 10-15 years. Systems operate 50-100 channels per fiber and with 50-100 fibers per communications bundle. Each wavelength channel operates a... View full abstract»

    This article discusses the prospect of free- space optical links (FSOLs) in relation to backhaul applications as well as its technology trend, including the recent development of radio on free-space optical links (RoFSOLs). Here, we consider how FSOLs act as useful transport media, focusing on practical experience in mobile backhaul networks. We refer to studies on FSOL conducted by the Internatio...

    A high TOI C-band MMIC amplifier has been developed using Cobham's multifunction self-aligned gate MESFET technology. The medium-power amplifier demonstrated 48-dBm OTOI, greater than 0.6 W saturated power, and 45% PAE performance. This outstanding TOI performance was only possible because of the SF configuration. The amplifier has approximately 3-dB higher gain than a single FET, which also resul... View full abstract»
