NASA starts wind tunnel tests for its quiet supersonic jet

From Engadget: 

NASA's plans for a quiet supersonic jet, the QueSST, just became tangible: the agency and Lockheed Martin have started wind tunnel tests for the future X-plane. It's a scale model at this stage, but it will be subjected to winds as high as Mach 1.6 (950MPH) to gauge both its aerodynamic performance as well as parts of its propulsion system. The tests should run until the middle of 2017.

We're seeing the campaign for satellites to help propel the development of new 5G data speeds. Check out this interview with Magali Vassiere, Director of Telecommunications and Integrated Applications on ESA's partnership with the industry to develop and demonstrate the added value that satellite brings in the context of 5G.

64 to 71 GHz Low Noise Amplifier (LNA)

New from HXI Millimeter-Wave components - The HLNAV-609 Low Noise Amplifier covers the frequency range from 64 to 71 GHz. MMIC technology is employed for high reliability and repeatability. The amplifier package provides WR-15 waveguide interfaces in an in-line configuration using the standard UG-385/U flange. The amplifier can be used in receivers for communication and radar systems and also for amplification in test equipment. The LNA contains a voltage regulator and bias sequencing circuitry allowing the use of a single bias to power the amplifier.
