New Power Amplifier Delivers Reliability and Consistency
Teseq has expanded its broadband amplifier line to include a new Class A model that operates from 10 kHz to 400 MHz with a saturated power level of 110 W. The CBA 400M-110 uses gallium arsenide (GaAs) integrated circuit technology to provide better compression characteristics and increased efficiency.The new power amplifier is designed for demanding EMC testing environments … [Read more...]
Designing Electronic Systems for EMC: Grounding for the Control of EMI
There are two primary reasons for grounding devices, cables, equipment, and systems. The first reason is to prevent shock and fire hazards in the event that an equipment frame or housing develops a high voltage due to lightning or an accidental breakdown of wiring or components. The second reason is to reduce EMI effects resulting from electromagnetic fields, common impedance, … [Read more...]
A Time-Domain EMI Measurement System Up to 26.5 GHz with Multichannel APD Measuring Function
I. INTRODUCTION The advances in radio systems in the past and their ongoing progress has been joined by advances in measurement systems and, hence, they require further development of measurement and specification standards. Electric and electronic systems have to be designed and realized such that the escape of unwanted electromagnetic energy into the environment is … [Read more...]

MYTH: Is it Possible to Get Energy for Free?
Sir Isaac Newton said that energy can't be created or destroyed, but he didn't establish any laws about paying for it. Countless scientists and inventors have since proposed free energy recipes, and MythBusters Jamie Hyneman and Adam Savage cooked up a handful, including a G-strain amplifier, a Minto wheel and the Bendini motor, and took them for a test run. Find out what … [Read more...]
