Although not strictly an EMC standard, the efficacy of this new 4G specification will determine the quality of WiFi communications in an ever more crowded spectrum. The 3rd Generation Partnership Project, or 3GPP, has settled on the final specification for the upcoming fourth generation (4G) Long Term Evolution (LTE) for WiFi, which is expected to form the backbone of mobile … [Read more...]

CISPR Specification on Ancillary Apparatus and Measurement of Radio Disturbance
CISPR 16-1-4 Ed. 2 (2008-01) is entitled "Specification for radio disturbance and immunity measuring apparatus - Part 1-4: Radio disturbance and immunity measuring apparatus - Ancillary equipment - Radiated Disturbances." This part of CISPR 1600 is considered a basic standard, which specifies the characteristics and performance for the measurement of radiated … [Read more...]
Fundamentals of EMC Design: Our Products Are Trying To Help Us
INTRODUCTION We often design electronic products only to find that when we test them for electromagnetic compatibility (EMC), their emissions and/or immunity are not as good as we need them to be. Usually, at this time, we feel as if we are fighting against the laws of physics to contain the conducted and radiated emissions, or to reduce susceptibility. But in fact the laws of … [Read more...]
CST, Delcross Demonstrate Integrated Solution for Cosite Interference Analysis

Navy Seeks to Develop Integrated Radar Antennas to Reduce RF Interference
Shipboard radar experts at the U.S. Office of Naval Research (ONR) are asking a select group of 18 U.S. defense contractors to turn their attention to advanced shipboard radar technology that reduces the number of radar antennas on Navy ships by using integrated, multi-function, multi-beam arrays. ONR officials issued a request for information for the Integrated Topside … [Read more...]

Simple Method for Predicting a Cable Shielding Factor, Based on Transfer Impedance
For a shielded cable, an approximate relationship valid from few kHz up to the first cable resonance can be derived from its Transfer Impedance (Zt) allowing to predict the cable shielding factor. This Cable Shielding factor, as a figure of merit, is often preferred by engineers dealing with product specifications and early design. Being not necessarily EMC specialists, they … [Read more...]
