Low-Loss RF Coax Cable Assemblies

Crystek’s 50-GHz low-loss RF cable assemblies feature corrosion-resistant 2.4-mm 303 stainless steel connectors and three levels of shielding for low attenuation (loss) over distance (1.44 dB/ft at 50 GHz). They are in stock in standard lengths of 24, 39.4, and 48 in, with custom lengths available. The assemblies are suited for high-frequency interconnects in mission-critical applications and microwave laboratories.

Designing Quieter Aircraft via Acoustic Simulation

Greater fuel efficiency and low emission requirements have grown into such an urgent imperative in aircraft design that it often overshadows an equally significant factor in air travel—noise. Airbus shows that it’s possible to infuse acoustic simulation into design processes from beginning to end, giving engineers the acoustic simulation intelligence they need to create quieter aircraft, according to Free Field Technologies.

All Navy aircraft must go through electromagnetic interference testing to ensure that they can operate safely in the ship environment. In preparation for ship-board flights, the Northrop Grumman Corporation’s MQ-8C Fire Scout will be tested for its ability to operate safely in the intense electromagnetic environment aboard U.S. Navy ships. The MQ-8C Fire Scout uses specially designed Faraday cages to protect the aircraft’s sensitive equipment from signal interference.

Unmanned Aircraft Must Rise Above Barriers for Commercial Applications

Historically, the unmanned aircraft system (UAS) market has been dominated by military applications from surveillance to active engagement. In the near term, the market’s military focus is expected to continue. However, with projected growth from around $6 billion today to nearly $12 billion in 2023 (according to the Teal Group), large-scale commercial adaptation is not only possible, but likely.
