Boonton Launches USB Microwave Power Meters

Boonton announces the launch of the first two members of a new USB Power Meters series: the 52012 and 52018. Extending its product portfolio with the 52000 series family, Boonton is now providing reliable entry level USB controlled CW Power Meters. The new meters offer a frequency range from 10.0 MHz to 12.4 GHz or 18.5 GHz and allow accurate power measurements between -50 to + 20 dBm. The VSWR is better than 1.25:1 at a 50-ohm impedance.

Where Will WiMAX Go?
By Jack Browne, MWRF Technical Director

One of the breaking news items below, from the solid research firm ABI Research (www.abiresearch.com), notes the rapid growth of Long Term Evolution (LTE) technology for broadband services, such as broadband wireless access (BWA) applications. The number of base stations to be installed in a few short years is certainly impressive, implying a large number of mobile subscribers for the LTE outgrowth of 3G cellular networks.

Assuming even conservative numbers based on these ABI Research market forecasts, what does this imply for the future of WiMAX technology? Having pored through the various versions of the IEEE 802.16 standards for both fixed and mobile WiMAX technology, there is not doubt that this is a beautifully designed wireless technology making the most of orthogonal-frequency- division-multiple (OFDM) techniques to gain bandwidth efficiency even in the less-than- desirable, multipath-infested environments typical of wireless metropolitan area networks (WMANs).

In fact, based on those standards, and on the work of industry organizations such as the WiMAX Forum (www.wimaxforum.org), there is no reason to believe that WiMAX will fail to deliver on its promise of reliable fixed and mobile BWA services. In fact, WiMAX can also co-exist with other wireless technologies, such as UMTS, 3G LTE, and IEEE 802.11 WLANs, and is designed to do so. In the end, it is probably safe to say that WiMAX will go where you go.

The Thermal Management Imperative in Defense Electronics

News

Report Predicts LTE Growth

Almost 300,000 base stations using the broadband wireless technology long as Long Term Evolution (LTE) will be built by 2014 according to a report just released by research specialist ABI Research. LTE, essentially a mobile wireless variant of WiMAX, will make use of advanced modulation formats such as orthogonal-frequency-division-multiplexing (OFDM) techniques to compete with WiMAX as a wireless means of delivering broadband, multimedia services to mobile devices. The report, "UMTS Long Term Evolution" reviews the market for LTE and includes forecasts for the market potential extending to 2014. The report covers base transceiver station (BTS) installations, BTS additions, and BTS capital expenditures.

SPI Raises The Bar On DSP Performance

Fabless semiconductor house Stream Processors, Inc. (SPI) specializes in parallel-processing architectures for digital signal processors (DSPs), such as their new Storm-1(TM) SP16HP. The software-programmable DSP achieves 112 billion multiplications and accumulations per second (GMACs/s) for 16-b operation and 448 billion operations per second (GOPS) for 8-b operation. Designed as a cost-effective C-language-programmable alternative to multiple-DSP designs and field-programmable gate arrays (FPGAs), the SP16HP employs a single-core programming model to avoid the synchronization issues associated with multiple-core processors. The new DSP is priced at $149 each in 10,000 quantities.
