December 2011 Standards Expand For Enhanced Performance Wireless communications standards are constantly in flux, with standards bodies such as the Institute of Electrical and Electronics Engineers (IEEE) and the International Telecommunications Union (ITU) seeking to test the limits of different operating frequencies, bandwidths, and modulation formats. — Jack Browne December 2011 Transistors Pick Up Speed With GaAs Microwave semiconductors have come a long way in a short time. — Jack Browne 50th Anniversary Issue Broadcasting Harnesses The Digital Age Although broadcasting has been around for more than a century, it has only been associated with digital technology for the last 10 to 15 years. — 50th Anniversary Issue LTE Sets Foundation For Mobile-Broadband Services 2011 was another milestone year in the evolution of mobile communications, as the first fourth-generation (4G) Long Term Evolution (LTE) networks became commercially available. — 50th Anniversary Issue Radar’s Range Extends Through Technology Radar concepts date back to some of electronics’ legendary figures, such as James Clerk Maxwell and Heinrich Hertz. — Nancy Friedrich 50th Anniversary Issue MUOS Heralds Future Of Military Satcom Today, nearly every person in America relies on satellites for one function or another. — Mark Pasquale 50th Anniversary Issue Cobra Judy Replacement: The Legacy Continues Cobra Judy was developed in the 1970s to provide the government with long-loiter, ballistic-missile data-collection capability in support of international-treaty monitoring activities. — October 2011 New Tacks Are Taken To Roll Out 4G Infrastructure Fourth-generation (4G) cellular service has begun to roll out in earnest. — Janine Love October 2011 Cellular Expansion Fueled RF Industry Wireless technology has become a way of life, with wireless devices available for telephone communications, for data/computer communications, and even for downloading entertainment in the forms of movies and video games. — Jack Browne October 2011 Novel Topology Supports Wideband Passive Mixers Choices for frequency mixers capable of wide spurious-free dynamic range (SFDR) and broadband performance are often limited. — October 2011 Satellite Communications Were Expected To Fill Broad Cellular Gaps Cellular devices and technologies are certainly prevalent in consumers’ daily lives. — Nancy Friedrich September 2011 Advanced Radios Strengthen Battlefield Communications Battlefield radios are essential tools for tactical communications, but many older radios are simply wearing out. — Janine Love August 2011 Shrinking Cells Impact Base-Station Design Cellular Communications continues to experience a worldwide growth trajectory. Consequently, the need for base stations also continues to grow. According to Strategy Analytics, Inc., traditional macro and micro-cell base-station deployment will peak at slightly over 1 million base stations per year in 2012 before falling to slightly less than 1 million in 2014. However, the company sees explosive growth for... — Janine Love August 2011 Bracing For The Cellular Explosion CELLULAR COMMUNICATIONS has become an essential facet of life for most people. But those of the “older generations” can certainly remember a time without cellular telephones—in popular culture, think back to Clark Kent racing into a telephone booth to change into Superman. Today, the telephone booth has become a technological victim of the cell phone. Portable two-way communications has been available in the form of hand-held radio transceivers ... — Jack Browne August 2011 Cold-War Cooperation Birthed Search And Rescue System Since 1982, NOAA’s Search And Rescue Satellite Aided Tracking (SARSAT) System has rescued more than 28,000 people worldwide. — Nancy Friedrich June 2011 SDRs Grow As Flexible Communications Devices Software-defined radio (SDR) technology is entrenched in many military applications, but has also made its mark in commercial applications, notably in amateur-radio and short-wave-radio markets. The radio approach, which employs digital signal processing (DSP) in place of functions formerly handled by analog hardware, offers the potential for flexible interoperability among many different existing radio platforms as well as the capability of... — Jack Browne June 2011 1970s Welcomed Radar And Communications Firsts Multimode radar systems have grown extremely sophisticated with advances in RF and digital signal processing (DSP). These systems have been in operation since the late 1970s, although in more basic form. In the May 1977 News section, MicroWaves charted the flight tests of the first multimode F-16 radar. It boasted more operating modes than previous airborne fighter radars of its kind. Among them were the now-common high-resolution... — Nancy Friedrich May 2011 Licensed UHF Radios Link Machine Systems COMMUNICATIONS between machines is becoming almost as important as communications between people, as evidenced by the proliferation of industrial automation. With growing reliance on automated equipment for quality of life in many areas, including in critical infrastructure cases, the need to increase machine-to-machine (M2M) communications is growing steadily with time. Some of the same communications devices and networks that work for people can... — Jack Browne April 2011 Smart-Energy Solution Runs On 3G Network Smart-grid rollouts are either imminent or already taking root across the globe. In terms of what communications standards, infrastructure, etc. will be used to enable the smart grid, however, a “model” has not yet been fully defined. Although proprietary solutions are still being reviewed, wireless technologies like ZigBee and cellular networks also may have a role. At last month’s CTIA, for example, ... — March 2011 MEMS Platform Meets Mobile Market Needs DelfMEMS and KFM TEchnology are merging their talents to enable Delf- MEMS to provide a low-cost, RF microelectromechanical-systems (MEMS) technology platform and related products for mobile applications. Mobile products have rigorous packaging requirements regarding size, thickness, cost, integration, overmolding protection, and performance. By combining the technology from both companies, R&D teams will be able to adapt the packaging to the switch configuration. In... —  prev. page
