Ceramic Feedthrough Filters: Winning the Finite EMI Fight (.PDF Download)
April 10, 2020
From laptop computers to home-security systems, the transmission and reception of RF or microwave signals from one device to another is crucial. The term used to identify the energy in these transmissions is electromagnetic radiation. Such radiation is around us everywhere, all the time, at frequencies ranging from 3 kHz to 300 GHz.
When electronic devices have internal operating processes that rely on signals in this RF frequency spectrum, unintended results may occur if the ever-present RF or microwave electromagnetic radiation interacts with the device. This occurrence is otherwise known as electromagnetic interference (EMI).
