Software-Defined Analog Filters to Modernize and Improve Radio Filters
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)
Abstract Worst-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...]
EMC Laboratory Selection Audit Items
Introduction This blog will provide the reader with an introduction to some of the items that need to be looked at when auditing an EMC laboratory with an eye to placing them on your company’s approved lab list. This is not an in-depth look at each item but is based on my experiences auditing laboratories (both in-house and 3rd party) over a number of years. Key … [Read more...]
