How to compare EMI absorption materials with a cookie tin
Product enclosures have frequency resonances that can produce unwanted EMI. Absorption materials in the cavity can reduce EMI. Use a cookie tin to compare materials before inserting them into your product. As operating frequencies approach microwaves, enclosures can appear as resonant cavities and amplify EMI emissions. When I was working on space shuttle communications systems, […]
mmWave sensor adds Wi-Fi HaLow connectivity for extended range IoT monitoring
Airfide Networks has released the AFN6843 micro-mobility occupancy sensor with Wi-Fi HaLow connectivity.
