In this article, a new Doherty amplifier using high-efficiency inverse class F and class F amplifiers is presented. The characteristics of inverse class F and class F amplifiers have been analyzed for their bias conditions and load impedances in order to identify their suitability to be the carrier or...

Total markets for terahertz systems are likely to surpass $1 B per year by the end of the decade, thanks to the availability of robust, relatively inexpensive terahertz systems that are capable of addressing the most high profile applications such as security, medical imaging and process control. A new...

Exalt Communications announced that the California Department of Forestry and Fire Protection (CAL FIRE) has deployed its microwave backhaul systems to support video surveillance for unstaffed lookout towers in El Dorado County. This unique application, the largest of its kind in the United States, allows CAL FIRE dispatchers in...

All radio frequency (RF) links are subject to distortion due to the physics of the transmission media, as well as the physical environment in which the link is operating. While designers take these effects into account when developing communication systems, actual testing with these distortions realistically applied to the...

EADS North America Test and Services , a division of EADS North America Inc., announced it has acquired Trig-Tek Inc. , a Garden Grove, CA-based company, providing precision, dynamic test and measurement instruments for the US aerospace and defense markets. The acquisition of Trig-Tek is consistent with EADS' strategy...

"The year 2009 may have started with a whimper but by 4Q-2009 the global mobile handset market ended with a pretty reasonable bang," says Jake Saunders, Vice President for Forecasting at ABI Research. "We estimate 336.5 million handsets were shipped in 4Q-2009, up 15.1 percent QoQ." Competition continued to...

Plessey Semiconductors' facility in Plymouth. A famous name has been resurrected following the bold decision taken by the management teams from Plus Semi in Swindon, UK, and the former X-FAB facility in Roborough, Plymouth, UK, to re-launch Plessey Semiconductors Ltd. The company has been created from the acquisition of...

ITT Corp. announced a strategic realignment of its defense segment, a move designed to better align the company with the emerging needs of its expanding global customer base, which is increasingly integrated and network-centric. The realignment will enable better integration of its product portfolio, encouraging a more coordinated market...

Next generation wireless systems are moving towards ever increasing data rates, higher spectral efficiency and improved quality of service. This development has largely been facilitated by advanced terminals with multiple antennas. However, the use of multiple antennas not only opens up new opportunities, but also presents new testing challenges....

S-parameters have been used to represent linear networks for simulation and design since the 1960s. Measuring S-parameters was made possible with the introduction of the network analyzer. Designers could then integrate S-parameter "black-boxes" along with other electrical components using linear frequency-domain simulators. The measure, model and simulate triumvirate has...
