Filters are some of the most common components found in wireless system designs. They are typically used to block interference from various sources. As limited spectrum resources are allocated to ever increasing number of users, more conflicts between these users arise and more filters are constantly needed. Nowadays, interference is quite common between cellular base stations, … [Read more...]
Cable Discharge Event (CDE)
AbstractWorst-case Cable Discharge Events (CDE) are poorly understood by most of the product developers as the definition of what is about to happen when you plug in a cable into an appliance’s socket. It is NOT the electro-static charge which could be expected on the cable: outer/inner shield(s) + internal wires, while the cable is fully floating prior to the cable … [Read more...]

Electrostatic Discharge (ESD) in Electro-Optic Devices
Many electronic components used in highly technological devices can be damaged or degraded by sudden electrostatic discharges, known by the term Electrostatic Discharge (ESD). Components such as transistors, diodes, laser diodes, electro-optical devices, and a variety of integrated circuits are all sensitive to electrostatic discharge. Many manufacturers are increasingly … [Read more...]
