Half Watt RF Driver Amplifier
Analog Devices, Inc. has introduced the ADL5324 half-Watt RF driver amplifier. The ADL5324 offers superior power efficiency and temperature tolerance. The ADL5324 operates over a wide temperature range (-40° C to +105° C), and can be biased to operate on less power. In addition, the ADL5324 features dynamically adjustable bias which allows RF designers to set the driver’s power … [Read more...]
High Optical Output IR Emitters
Opto Diode announces the third in the family of three super-high-power infrared (IR) emitters. Based on gallium aluminum arsenide (GaAlAs) technology, the new OD-250 features a wide angle, very uniform optical beam with ultra high optical output. Total power output is 250mW (typical) with a minimum output at 160 mW. Peak emission wavelength is 850nm, making this IR emitter … [Read more...]
Thyristor Module for Single-Phase PFC
The TDK Corporation has extended its range of EPCOS thyristor modules for dynamic PFC. The new TSM-LC-I module now also allows single-phase PFC of networks with rated voltages from 230 to 525 V AC. Depending on the voltage, the new module is designed for reactive powers of between 10 and 22 kvar. 110 V AC versions are available upon request. The EPCOS TSM-LC-I is characterized … [Read more...]
Multi-Tone RF Test System Tests Reduces Radiated Immunity Testing Time
AR RF/Microwave Instrumentation is introducing a new Multi- tone RF Test System, model MT06000 (80 MHz – 6 GHz), includes all the necessary instruments to perform radiated immunity testing per IEC 61000-4-3 except the required amplifiers, antennas and directional couplers. Amplifiers are selected and sized based on your required field levels and testing needs.The system mimics … [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...]
Eliminating the Need for Exclusions Zones in Nuclear Power Stations
Utilities operating nuclear power plants have been dealing with electromagnetic interference (EMI) problems for over two decades. Many early problems that affected the operation of instrumentation and control (I&C) equipment in plants stemmed from the use of wireless transmission devices (WTDs) (e.g., radio walkie-talkies, cellular phones, etc) inside the plant in the … [Read more...]
CISPR 32: New International Standard on Electromagnetic Emissions from Multimedia Equipment
In late 2011, The International Standards Commission's (IEC's) Special Committee on Electromagnetic Interference (CISPR) passed a Final Draft International Standard (FDIS) which had been under development for a number of years. The FDIS was actually developed by CISPR's Subcommittee I - Electromagnetic Compatibility of Information Technology Equipment, Multimedia Equipment … [Read more...]
The HF Current Probe: Theory and Application
This article describes one of the most valuable tools in the EMC engineer's “bag of tricks” – the high-frequency current probe. Current probes are invaluable for measuring high-frequency common-mode (or “antenna”) currents flowing on wires or cables. Experience has proven that poorly terminated (bonded or filtered) cables are the no. 1 cause for radiated emissions failures at a … [Read more...]
