Optimized Placement of Microwave Absorbers on High Speed Digital Channels

Laird has published a white paper containing evidence why effective placement of microwave absorbers can meet design requirements of today’s thinner, smaller, cramped-for-space mobile devices and other densely configured systems.

In it, Laird, an electronic component manufacturer, describes testing which suggests correct absorber placement at the board level can reduce the disruptive effects of electromagnetic (EM) radiation or “noise” without causing a deterioration of the digital signal of the link. The paper was co-authored by Laird Senior Staff Scientists Paul Dixon and Mohammad Ala Khorrami along with Todd Steigerwald and Haris Chowdhry of Advanced Micro Devices, Inc. It was presented at DesignCon, an industry event in Santa Clara, Cal.

Authors discuss the placement of appropriate microwave absorbers as a potentially reliable solution to meet required EM emission goals of a design team, helped by the dissipation of extra electromagnetic energy into heat.
