What Happens When Stripline Signals Cross Split Power Planes

Many claim that for stripline, it is ok to cross a split power plane, so long as the other adjacent reference plane is solid. Some others claim if there is an adjacent solid reference plane, less than 5mils away under the split, crosstalk will be mitigated. Read on to see an investigation into what really happens when stripline signals cross split power planes.

Characterizing & Debugging EMI Issues for Wireless and IoT Products

An increasing number of manufacturers are adding or retrofitting wireless technology into new or existing products. These products typically include mobile, household, industrial, scientific, and medical (ISM) devices. This transition towards “everything wireless” is in full swing, and with it comes problems with electromagnetic interference (EMI) from the product itself interfering with sensitive on-board cellular, GPS/GNSS, and Wi-Fi/Bluetooth receivers. Read on to find out what to do about it.
