In the commercial and technological arena, Asia is the continent that elicits strong opinions and provokes debate. Is it an all-consuming predator with an insatiable appetite, sustained by low-cost mass production, intent on devouring the lion’s share of the market? Or is it the goose that will lay and...

Mercury Computer Systems Inc. announced that it was selected by Raytheon to provide the wideband modem subsystem platform as part of Raytheon’s recent HDR-RF Ground Modem contract from the US Air Force. Raytheon worked with Mercury Computer Systems to leverage the benefits of commercial off-the-shelf (COTS) software radio processing...

TRAK Microwave Corp. announced that it has been awarded a contract from Raytheon Integrated Defense Systems (IDS), Andover, MA, to supply several critical components for the DDG 1000 Zumwalt Program. The DDG 1000 is the lead ship of a class of next-generation multi-mission surface combatants tailored for land attack...

MI Technologies announced it has received a $9.9 M contract from Lockheed Martin MS2’s Radar Systems business to design and build a radar test and measurement system in support of the Medium Extended Air Defense System (MEADS). MEADS is a mobile air and missile defense system designed to replace...

When peering in at the still-evolving world of WiMAX from the outside, it is easy to be confounded by the cloud of information swirling around as the technology works to launch itself into the mainstream. To the layperson, it is possible to conclude that WiMAX has already become hopelessly...

Long Term Evolution (LTE) is the project name given by 3GPP to the evolution of the UMTS 3G radio standards. The original UMTS Terrestrial Radio Access (UTRA) is based on W-CDMA technology, which has been continuously enhanced to include HSDPA & HSUPA (HSPA). The work on UMTS continues in...

The generation of ultra-wideband (UWB) waveforms is of great interest for applications ranging from communications to position sensing. Research and development engineers working in UWB are faced with the challenge of generating unique waveforms that meet their application requirements. Often this also requires high-performance waveforms (very fast transition times...

When communication systems are established engineers must account for numerous real world effects and maintain reliable communication systems. Information such as path loss from the transmitter to the receiver, immunity to interference (calculating and testing the effects of non-intended signals on the intended communications signal or effects of a...

In order to communicate with cellular phones and other wireless terminals, wireless communications base stations include an RF power amplifier which feeds a high frequency, high power signal to the external antennas. In today’s systems, the power amplifier function is generally designed by cascading and paralleling several RF transistors...

Any product today that can both save money and save space is a much needed commodity in today’s communication system designs. With systems getting ever more compact, board real estate is at a premium, hence the drive to integrate more functions in less space and keep the support structure...
