Think Tank Calls for Rethinking Spectrum Use

 

As new faces and new ideas move into the executive suite at the FCC, the Washington, DC-based New America Foundation has issued statements and papers bringing to the fore two longstanding and contentious issues—achieving wide broadband access by freeing spectrum for wireless connectivity and by relying on “opportunistic access” or the smart radio technologies. In “The End of … [Read more...]

Ferrite Chip Bead Arrays Suppress Signal Line Noise

 

The Type FBA denotes a multilayer ferrite chip bead array from KOA Speers Electronics that retains all the features of multilayer ferrite chip beads. It suppresses noise in signal I/O lines and other circuits that require multi-bead noise suppression. The single-package FBA conserves PCB “real estate” and helps to reduce assembly costs. The series is available in a wide range … [Read more...]

Power Module Incorporates EMI Filter for Use in Medical Equipment

 

The ISL8201M from Intersil is a highly integrated power conversion module. It provides a high efficiency, low-noise DC/DC power solution in a thermally enhanced QFN package. Its onboard input filter supports low noise operation and reduced EMI. The small form factor of the ISL8201M conserves board space, and its integration of functions cuts procurement and placement costs in … [Read more...]

Téléphone Cellulaire—Non!

 

Recently France banned cell phone use in its primary schools based on the “cautionary principle” that the long-term health effects of being exposed to the EM fields from cell phones from childhood on is still an unknown. At present cell phone use is allowed on school grounds but not in classrooms. Under the new regulations, their use in primary schools is simply banned. French … [Read more...]
