This article presents the design approach and test results of a X-/Ku-band 4-bit compact GaAs MMIC phase shifter developed for broadband applications. The phase shifter design is based on choosing an optimum topology for each bit, yielding compact size and low insertion loss. It also has on-chip integrated digital...

Scientists and engineers from around the world recently met in Australia to begin the preparatory phase for the biggest project ever undertaken in radio astronomy. The international Square Kilometre Array (SKA) will be 50 times more sensitive than any existing facility and will probe some of the biggest questions...

The European Space Agency and Astrium have signed a €195 M contract to provide the first Sentinel-2 earth observation satellite, devoted to monitoring the land environment, as part of the European Global Monitoring for Environment and Security (GMES) programme. As prime contractor, Astrium is responsible for the design, development...

EPCOS, a manufacturer of electronic components, modules and systems, has acquired the activities of NXP Semiconductors Netherlands B.V. in the area of Radio Frequency Micro-Electro-Mechanical Systems (RF-MEMS). Through the acquisition EPCOS continues its strategy of cooperative ventures and acquisitions aimed at extending its technology and product range, boosting its...

Alcatel-Lucent, Ericsson, NEC, NextWave Wireless, Nokia, Nokia Siemens Networks and Sony Ericsson have made a mutual commitment to a framework for establishing predictable and more transparent maximum aggregate costs for licensing intellectual property rights (IPR) that relate to 3GPP Long Term Evolution and Service Architecture Evolution standards (LTE/SAE). The...

ANSYS and Ansoft Corp. have signed a definitive agreement whereby ANSYS will acquire Ansoft for a purchase price of approximately $832 M in a mix of cash and ANSYS common stock. Under the terms of the agreement, which was unanimously approved by the Boards of Directors of both companies,...

Engalco has recently released an industry and markets report covering global military and space-related systems. “Microwaves Global Military and Space Systems” (MGMSS) provides “free world” market forecasts for microwave electronic module products sold into these segments. The report separates products and applications into microwave (0.7 to 20 GHz) and...

It was once easy to distinguish a cellphone: it had a phone number, was used for voice service and offered short message service (SMS) text messaging. Many cellphones also include third-generation (3G) network access to download rich media files and streamed content. Wi-Fi networks, however, have become more prevalent,...

Automated systems designed to help drivers avoid accidents are starting to become available on a wide range of vehicles. In these first generation systems, the assistance is mostly limited to flashing lights and audible/haptic signals. OEMs and suppliers are working hard to develop reliable technology that does not irritate...
