Fighting stray frequencies in PCBs
To meet the constant consumer demand for higher bandwidth in their wireless devices, companies have developed ultra-wideband communications equipment and advanced wireless techniques, such as frequency-hopping spread spectrum transmission, in which radio signals are rapidly switched between frequencies. The same technique can also guard against eavesdropping. With those advances, however, comes a growing challenge for manufacturers of the high-performance printed circuit boards aimed at the wireless communications market. That challenge lies in controlling a phenomenon known as Passive Intermodulation.

Ensure authenticity by eliminating counterfeit parts
Counterfeit electronics are becoming increasingly common in the marketplace. These counterfeits can lead to problems with product safety and reliability, a risk for end users of the products that incorporate them. It’s possible, however, to minimize the problem by being aware of it and taking proper steps to identify parts and mitigate the issue.
