Leveraging highly integrated RFIC designs and high dynamic range converters helps meet the challenges of next-generation base stations. By Phillip Halford and Ed Balboni, RF Group, Analog Devices, Inc. click to enlarge Figure 1.
By Manuel Uhm and Mark Quartermain, Xilinx The baseband processing function represents a key area of product differentiation for Telecommunications Equipment Manufacturers (TEMs). However, the advent of 3.9/4G systems poses a difficult challenge to TEMs, as they struggle to evolve traditional DSP-centric channel cards to meet a new set of technical and commercial challenges.
For deployments by a single operator, wireless repeater systems offer more cost effective fiber transport costs. By Allan Evans, VP of Marketing, Samplify Systems ABI Research predicts that revenues for distributed antenna systems and in-building wireless systems will exceed $15B by 2013.
The current generation of monitors are portable heart rate sensors that have found their way into general purposes for activities such as exercise and sports. While these devices are useful for individual purposes, they do not facilitate use by a coach or manager. By Archana Yarlagadda, Cypress Semiconductor click to enlarge Figure 1.

By Vandana Lokeshwar, Newark Engineers need to consider op-amp noise in designs for an increasing variety of applications. Today's world is challenging engineers to do more with less; to create new products that will help users improve aspects such as productivity or quality of life while consuming fewer resources such as fuel, finance or time.
Nancy Maas Editor-in-Chief The holiday season is upon us once again and, as usual, we are subjected to the onslaught of catalogs, fliers, commercials and emails touting us to take advantage of the deep discounts merchants are offering for their wares.
Making measurements involving MIMO applications requires adaptation of the algorithms used in the analysis software. By Johan Nilsson and Dr. Wolfgang Wendler, Rohde & Schwarz click to enlarge Figure 1. MIMO in WiMAX system. Due to ongoing growth in demand for channel capacity, more and more radio standards such as WiMAX, 3GPP HSPA, 3GPP LTE and WLAN are adopting MIMO technology.
ASSPs are meeting the challenges through the integration of mixed-signal technology and innovative power management schemes. Herve Branquart, Robert Waterman, ON Semiconductor click to enlarge Figure 1: Two way RKE block diagram Wireless transceiver technology is truly established in the automotive industry with Remote Keyless Entry (RKE) now a standard feature of even basic specification vehicles.
Hybrid Electric Vehicle (HEV) development requires collaboration and optimization across multiple engineering domains. By Saurabh Mahapatra, The MathWorks Figure 1: This simplified diagram of an HEV vehicle illustrates one possible arrangement of system elements.
An integrated single-chip RF transceiver provides the flexibility to address all aspects of the LTE standard. By Ebrahim Bushehri, Lime Microsystems click to enlarge Table 1: Comparison of data rate and channel bandwidth for wireless standards.
Welcome to Brainstorm! While Wi-Fi technology has proven to be largely successful in providing inexpensive wireless Internet service within close proximity to the Wi-Fi access point, WiMax technology could expand the potential of wireless penetration and connection quality. Ashish Sharma, VP Corporate Communications, Alvarion Wi-Fi technology has proven very successful for short range broadband connectivity for hotspots, residential homes and enterprises all around the globe, providing inexpensive wireless internet service within close proximity to the Wi-Fi access point through the use of license-exempt frequency bands.
Welcome to Brainstorm! The detection of counterfeit components has become increasingly difficult. The majority of parts have the same or similar markings as their qualified counterpart. In many cases, the identification of major manufacturers is applied despite manufacturers' efforts at product differentiation.
With recent technical advancements, MLVs can now be used throughout the growing number of modules and interfaces in under hood automotive applications. By Ron Demcko, AVX click to enlarge Figure 1. Integration Capacitor Charge Calculations.
