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...

WiMAX Poster and Brochure Agilent now has available a new poster and brochure. The wall poster is designed as a reference tool to help engineers understand the evolving communication standard by describing detail and contrasting fixed and mobile WiMAX technologies. The eight-page full-color brochure describes Agilent’s portfolio of design...

Andrew Corp. and Nokia Siemens Networks have agreed to revise their long-standing relationship in custom filter production. The agreement provides more design and manufacturing control to Nokia Siemens Networks, supported by Andrew’s research and development expertise, as it readies to market its next generation radio frequency filter products. Under...

Skyworks Solutions Inc. , an innovator of high performance analog and mixed signal semiconductors enabling mobile connectivity, announced that given heightened demand for its products from tier-one handset OEMs and a diverse set of analog customers, it is expanding its manufacturing capacity. Skyworks has already commenced the conversion of...
