And The CM Currents Go Round and Round

 

When we were discussing green electron current (differential mode) in the last post, I mentioned that common mode (CM) currents (red electrons) are typically caused by unbalanced differential mode (DM) currents.  It’s pretty easy to visualize that in an unbalanced differential transmission system, one of the traces is longer, has an extra via, needs a branch, the spacing … [Read more...]

FCC to Exceed Goal of Freeing 300 MHz for Mobile Wireless Broadband by 2015

 

A Federal Communications Commission official has reported to Congress that the agency will exceed its goal of freeing up 300 MHz of spectrum for mobile wireless broadband by 2015. Ron Repasi, deputy chief of the FCC’s Office of Engineering and Technology, discussed the FCC’s progress at a recent hearing on "The Role of Receivers in a Spectrum-Scarce World." According to … [Read more...]

Evolution of Wireless Technology May Affect GNSS Over-the-Air Testing

 

The evolution of wireless communications technology, in combination with the incorporation of GNSS positioning into mobile devices and the increasingly crowded frequency spectrum, is increasing reliance on over-the-air testing and forcing the creation of new specifications, standards and testing procedures for electronic devices. Consumer electronics continue to strive for … [Read more...]
