Inductor Tuning Method Could Shrink Cell Phones
Scientists at Northeastern University in Massachusetts have devised a new method of tuning radio frequency circuits that could reduce the size and improve the performance of smartphones and other RF devices. “Every radio-frequency resonance circuit has two components: an inductor and a capacitor. [However,] for the many decades that we've been using RF devices, we've only been … [Read more...]
Boeing Demonstrates New Anti-Jamming Technology
New anti-jamming technology tested by The Boeing Co. earlier this week may make it easier and less expensive for the U.S. military to send secure communications via existing satellites. During the Dec. 15 demonstration, Boeing sent a protected signal through the sixth Wideband Global SATCOM (WGS-6) satellite. Engineers confirmed that the signal met all targets for accuracy and … [Read more...]
