Published November 9, 2007 Harlan has selected one question from his "Ask Harlan" column to be featured in the November issue. Harlan will be monitoring the responses and will ultimately choose the best answer to the question. All of the responses to the featured question will be posted on...

EADS Defence & Security (DS) has awarded its 2007 ARGUS science prizes to five students achieving outstanding research results in communications and high frequency techniques. The award ceremony took place during the ‘Professor's Day’ at EADS DS's Defence Electronics’ facility in Ulm, Germany, which annually provides a platform for...

Triggered by strong market interest and supporting the growth of mobile broadband worldwide, Ericsson has announced the launch of infrastructure and device platforms for WCDMA/HSPA in the 2.6 GHz frequency band. The launch of HSPA products in the 2.6 GHz frequency band provides an immediate and secure choice for...

Indra , a leader in information technologies and defense systems, has acquired the Australian Interscan Navigation Systems (INS), whose main activity is the design and integration of ground-based infrastructure support equipment for the aerospace transportation sector (radio navigational aids). The company's turnover amounted to €6.4 M in the last...

Accton Wireless Broadband (AWB), headquartered in Taiwan, and the leading wireless broadband equipment ODM , has extended its relationship with terminal chipset provider Beceem Communications . Under the expanded relationship the parties will bring complete Mobile WiMAX Wave 2 terminal solutions to mobile WiMAX operators and Beceem’s infrastructure OEM...

With the Microwave Journal November supplement “WiMAX and Emerging Technologies” hitting the streets and the WiMAX World and European Microwave Week (EuMW) conferences still fresh in the minds of those who attended, now seems like a great time to consider the impact these utopian “wireless everywhere” systems will have...

In the 28 years that I have been both a user and designer of solid-state switches, I have witnessed some major technological advances as RF switches have developed from discrete PIN diodes and evolved through recent developments such as HMIC, GaAs MMICs and RF CMOS. Significantly, too, new technologies...

The use of discontinuities in ground planes or in microstrip lines is currently employed to improve the performance of different passive circuits, such as the size reduction of amplifiers, 1 the enhancement of filter characteristics 2,3 and applications to suppress harmonics in patch antennas. 4 On the other hand,...

With the continuous trend to reduce the size of electronic modules and increase the integration levels, the integration of passive elements within the interconnection board or substrate becomes more and more a key factor. In addition to size reduction, passive integration leads to assembly cost reduction as well as...

In modern wireless communication systems, miniaturized MMIC microwave bandpass filters are required to reduce the cost and decrease the RF system design time, especially for a single RF transceiver chip. Therefore, many studies on reducing the large size of conventional bandpass filters have been made. The lumped element approach,...
