SELEX GALILEO has opened its new Electronic Warfare Operational Support (EWOS) facility in Lincoln, UK, dedicated to the delivery of EWOS capability and products. Located at Alpha Court, on the western outskirts of Lincoln, the 1100 m 2 facility, which includes a 200 m 2 Radio Frequency screened laboratory,...

NEC Laboratories Europe , the European R&D centre for network technologies, was established as Network Laboratories in Heidelberg, Germany, in April 1998 and celebrated the landmark by holding a 10th Anniversary Symposium for around 50 invited representatives in various fields from universities and companies in Europe. NEC Laboratories Europe...

Alcatel-Lucent has signed a contract with Globacom , Nigeria’s second largest national operator, to extend the network capacity and performance of its mobile and fixed networks. The project, which is part of the operator’s IP network transformation, will enable it to extend the delivery of advanced mobile and triple...

Crane Aerospace & Electronics used Flomerics' Flotherm thermal simulation software to develop an unusual heatsink that works in the vertical or horizontal orientation. The heatsink is for a DC power subsystem for a commercial airliner. Developing an entirely new heatsink geometry that would have met the performance requirements would...

A pioneering navigation device which can tune into different satellite networks around the world is being developed by researchers at De Montfort University (DMU) Leicester, UK, in partnership with Nottingham Scientific Ltd. (NSL). NSL specializes in the commercial exploitation of Global Navigation Satellite Systems (GNSS) technology. Satellite navigation receivers...

This editorial is directed on the surface toward the specific question of why a microwave engineer should join the IRE Professional Group on Microwave Theory and Techniques. It is impossible to answer this question unless the reader is convinced of the worth of professional societies in general. The writer...

In order to improve the simulation accuracy of microwave circuit designs, an accurate active device model plays an important role for circuit simulations. According to previous studies, the BSIM models can precisely predict the characteristics of deep sub-micron MOSFETs at operation frequencies below 1 GHz for digital and analog...

The wireless and satellite communications communities have always been looking for power efficient radios. However, the power efficiency is greatly dominated by the efficiency of the RF power amplifier (PA) in the transmitting path. Recently, most of the communication systems being deployed or to be deployed in the near...

Personal wireless communications have recently gained wide popularity. Presently, the trend is to provide a wireless link to every kind of electronic device. In particular, there is a specific need for greater capacities and transmission speeds, which, together with a growing demand from users for more complicated services, require...

Microwave power devices, widely used in modern wireless and communications systems, must operate in a nonlinear mode in order to operate efficiently. Nonlinear operation means that the only valid way to test them is under actual operating conditions of DC bias, RF power and impedance. Small-signal S-parameters are not...
