16,000 Watt Solid-State Power Amplifier Released
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...]
Class D Amplifier Offers Optimized EMI Performance
A new Class D amplifier offers more output power, lower noise and purportedly unsurpassed EMI performance in the industry's smallest package. Maxim’s new amplifier's 0.3mm-pitch, 9-bump wafer-level package (WLP) features a no-connect middle bump to eliminate the need for expensive PCB technologies. This allows the use of single-layer PCBs for reduced manufacturing cost. The … [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...]

System Compatibility: An Essential Ingredient for Achieving Electromagnetic Compatibility and Power Quality for Lighting Control Systems
Philip Keebler, Kermit Phipps, Frank Sharp, EPRI Lighting Laboratory For years, lighting systems have been operating as stand-alone loads without the use of sophisticated lighting controls for energy savings in all types of facilities—residential, commercial, and industrial. Utilities and end users viewed lighting controls in the past as, luxury, systems that were used only … [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...]
