AR RF/Microwave Instrumentation has been packing more power into its solid-state amplifiers lately, while at the same time making amplifiers smaller, lighter, and more energy-efficient. The company has now exceeded its highest power amplifier with its new Model 16000A225 (10 kHz – 225 MHz).AR RF/Microwave Instrumentation has delivered the 16,000-watt amplifier to BAE Systems in … [Read more...]
EM Design Software Helps in Development of Contactless Power System
A contactless distributed power supply system for modular automation components is being developed by a team lead by Professor Hans-Peter Schmidt at The University of Applied Sciences in Amberg, Germany, with the help of Opera electromagnetic design software. The system uses magnetic induction to facilitate the transfer of power and data between an input coupling device and a … [Read more...]
Smaller, Compact Amplifiers Now Go Up To 1200 Watts
AR RF/Microwave Instrumentation has already reduced the size of its “S” Series solid-state amplifiers, making them smaller, lighter, more compact & portable without losing any power. The smaller size makes them more energy-efficient and a better value.Reducing the size while maintaining the power was a challenge; but now AR has added even more power to these smaller, more … [Read more...]

Westinghouse Installs Electromagnetic Compatibility Testing Chamber
Westinghouse Electric Company recently completed the installation of its semi-anechoic electromagnetic compatibility chamber to support the company’s Equipment Qualification group at its New Stanton, Pa., facility. The addition of the semi-anechoic chamber will provide EMC test capabilities to ensure that instrumentation and control, electronic and electrical equipment meets … [Read more...]
Differential Transfer Impedance of Shielded Twisted Pairs
Michel Mardiguian, EMC Consultant, Saint-Rémy-lès-Chevreuse, France The concept of Shield Transfer Impedance (Zt), introduced by S. Schelkunoff in 1934, is a very convenient parameter for the prediction and control of EMI coupling through cable shields. Although widely applied to coaxial cables against EMI susceptibility problems, the Zt parameter can be easily extended to … [Read more...]
Effective EMC Troubleshooting with Handheld Probes
EMC testing is an unavoidable part of the development cycle for electronic products. As clock frequencies continue to increase, radiated emissions get harder to control. In an ideal world, the R&D engineer would test the emissions from his product early in the design stage and retest frequently as design changes were made, just ass he tests whether his product meets its … [Read more...]
