Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
The U.S. Air Force and Lockheed Martin marked a milestone with the completion of manufacturing of more than 15,000 line replaceable units containing 36,000 GaN-based high power amplifiers (HPAs) for Space Fence.
Cree has added four new gallium nitride (GaN) high electron mobility transistors (HEMTs) to its product portfolio at Digi-Key, the sole distributor for Cree RF components. Respectively based on Cree’s high power density 50V, 0.25μm and 0.4μm GaN on silicon carbide (SiC) foundry processes, the new X-Band and S-Band components exhibit high efficiency, high power gain, and wide bandwidth capabilities.
The Raytheon Co.-led Cobra Judy Replacement (CJR) program surpassed expectations during its first tests against a live rocket launch on March 19. From approximately 100 miles off the Florida coast, the powerful X- and S-Band radars integrated onboard the USNS Howard O. Lorenzen (T-AGM 25) successfully acquired and tracked both stages of an Atlas V rocket launched from Cape Canaveral and collected all associated data.
