Automated Radiated Immunity Test System for MIL-STD 461
AR RF/Microwave Instrumentation’s latest automated system for conducting radiated susceptibility testing, the AS18027 AR System, has been specifically designed to perform automated testing for MIL-STD 461 requirements. The system will produce fields up to 50V/m at 1 meter distance from 1-18 GHz. It is comprised of a variety of components including one of AR's new dual-band, … [Read more...]
Temperature Stable Measurement ICs for Power Management
STMicroelectronics’ new single-chip high-side current-sense amplifier, TSC1021, simplifies the design of accurate measurement circuitry in electronic control units. The TSC1021 provides a common-mode operating range of 2.8V to 30V and the device can withstand a range of -32V to +60V on its input pins without damage, enabling the device to target a variety of applications. In … [Read more...]
Product Launch for New Range of Amplifiers
The formal product launch of MILMEGA's new range of amplifiers started with the training of 25 sales engineers from Toyo Corporation.The full training program was carried out at Toyo's Headquarters in Tokyo. Further launch meetings and training sessions are being arranged over the EU and Asia in the next few months. Learn more from Milmega. … [Read more...]
Measurements above 1 GHz in Time-Domain: Theory and Application
Christian Hoffmann, Technische Universität München, Lehrstuhl für Hochfrequenztechnik, Munich, Germany; Stephan Braun, GAUSS Instruments GmbH, Munich, Germany Arnd Frech, GAUSS Instruments GmbH, Munich, Germany; Peter Russer, Technische Universität München, Lehrstuhl für Nanoelektronik, Munich, Germany Time-domain electromagnetic interference (EMI) measurement systems are … [Read more...]
On the Radiation Patterns of Common EMC Antennas
Vincente Rodriguez, ETS-Lindgren LP., Cedar Park, Texas, USA Antennas have been used in EMC measurements since the early days. Knowledge of the antenna pattern was not a requirement of the standards. While MIL STD 461 and some SAE standards called for information on the half power beamwidth, most standards did not require any knowledge of the antenna radiation characteristics. … [Read more...]
Troubleshooting Radiated Emissions Using Low-Cost Bench-Top Methods
Kenneth Wyatt Wyatt Technical Services LLC Editor's Note: Click on the pdf icon at left for a printable copy of this article. Because time-to-market and budget factors often drive many of today’s high-tech designs, electromagnetic compatibility (EMC) issues often surface at the last moment in the design cycle, potentially delaying product introductions. Very often, simple … [Read more...]
Transistors Cover Full Frequency Bands for Wireless Base Stations
Freescale Semiconductor’s two new LDMOS RF power transistors allow wireless base station amplifiers to cover all channels in an entire allocated frequency band. The transistors are internally matched with low capacitance to simplify circuit design and have integrated electrostatic discharge protection. Their broad gate-source voltage range of -6 to +10V increases their … [Read more...]
Amp Adds Switches for Test Versatility
Rohde & Schwarz adds new functions to its R&S BBA100 broadband amplifier family to create a one-box solution. Integrated RF output switches and sample port switches allow the amplifiers to be used for many applications without the need for external switching matrices. Existing third-party amplifiers can also be integrated into the R&S BBA100 system. The modular … [Read more...]
Redesigned "S" Series Amplifiers Offer Coverage 4 – 18 Ghz
AR RF/Microwave Instrumentation has redesigned several of its "S" Series amplifiers to extend the bandwidth from 18 GHz down to 4 GHz. The models previously went down to 6 GHz. The redesigned amplifiers are:Model 5S4G18 (5 watts CW, 4 - 18 GHz) (formerly model 5S6G18A)Model 10S4G18 (10 watts CW, 4 - 18 GHz) (formerly model 10S6G18A)Model 20S4G18 (20 watts CW, 4 - 18 GHz) … [Read more...]
