Before deploying microwave and millimeter-wave devices and systems within 5G, the Internet of Things (IoT), and high-speed wireless communication, it is essential to predict their performance. This need has increased the demand for virtual test platforms through simulation software. High carrier and system bus frequencies are necessary for high-data-rate communication … [Read more...]
Knee Frequency is A Misleading Bandwidth Metric
INTRODUCTION There is a transmission line critical length rule that is often used in high-speed PCB design by novice engineers. This rule should not be used and is not appropriate for high-speed PCBs. The bandwidth limit of a digital signal or a high-speed digital channel is often used in certain calculations to get estimates of channel behavior. For example, the knee … [Read more...]
Placing a Metal Plate in Front of a EUT May Not Be Enough to Solve Radiated Emissions Exceedances or Radiated Susceptibility Failures
EXAMPLE OF AN EUT WHICH HAS FAILED RADIATED SUSCEPTIBILITY As described in reference 1, the EUT was exposed to a radiated immunity test at a level of 20V/m. The side which contained a vertical metal plate, with an approximately 0.3m x 0.3m dimension and which was electrically isolated from a metal baseplate failed at 12V/m and 300MHz. On the other sides of the EUT, … [Read more...]
New! UHS: Compact and Powerful SMD Fuse for High Current SELV Applications
Santa Rosa, California – SCHURTER announces the launch of its new UHS, a compact fast-acting SMT fuse designed to safely interrupt high-energy overcurrent in the SELV range. The new UHS is available in six current ratings from 50-100 A at 50 VDC or 32 VDC, with a breaking capacity of up to 2000 A. SELV, which stands for "Safety Extra Low Voltage," may sound straightforward and … [Read more...]

A Simple Guide to Antenna Selection
INTRODUCTION Selecting an antenna for testing can sometimes be straightforward but often requires some specific consideration. One aspect in antenna selection is knowing the intended test frequencies and then selecting a matching antenna. Not all antennas are created equal, and when it comes to frequency different antenna styles perform better at some frequencies and … [Read more...]
