Over the last few years, the transition from analog to digital RF technology has signaled the need for high performance digital logic at higher data rates. The evolution of high speed digital communication demands more emphasis on S-parameter measurements, the ability to measure lower jitter, and more widespread use...

Microwave engineers appreciate the need for different communication schemes to serve diverse channels and receivers. How information is transmitted directly impacts successful reception. In publishing today, print and the Internet are used to communicate to an intended audience. Where print is tried and true, the Journal ’s website is...

Nokia is one of the most familiar names worldwide, but not everyone is conversant with the fact that the company started out in 1865 with a mill producing paper—the original communications technology—and that it took a merger with a cable company and a rubber firm to set the new...

The ever increasing development of wireless communication systems has led to a great demand for mobile devices that can operate using different standards such as GSM, GPS, DCS, UMTS and wireless local-area network (WLAN). Moreover, for the standards working under a complicated environment such as WLAN, the polarization diversity...

Major advances in microwave device development in recent years have enabled a transition to solid-state power amplifiers (SSPA) for wireless communications and radar systems in microwave to millimeter-wave bands. In particular, SSPAs are rapidly replacing electronic tube amplifiers, such as magnetron and traveling-wave tube-based amplifiers (TWTA), for base stations...

Compact frequency synthesizers fill many needs in modern communications systems. To achieve full-sized performance in miniature packages, this research work describes a line of extremely compact frequency synthesizers that leverage a novel, patented voltage-controlled oscillator technology for the stability and low noise needed for emerging wideband, high-data-rate wireless communications...

Industry News Cobham announced that it has sold M/A-COM Technology Solutions (MTS) to John Ocampo for $30 M in cash, $30 M in senior loan notes secured on the MTS assets and $30 M dependent on future revenue in the period 2010 to 2012. The loan notes carry a...

The global credit crunch could endanger many large digital terrestrial TV deployment projects, which require large amounts of financed capital, reports In-Stat. This could cause delays in DTT conversion programs worldwide, with consumers purchasing fewer set top boxes (STB) as a result. “Another scenario, however, is more upbeat for...

The global recession may have drastically slowed many forms of economic activity, but not the efforts of mobile device manufacturers to drive growth by design innovation. “It is quite remarkable to see mobile handset trends in play,” says ABI Research Vice President Jake Saunders. “Despite the recession, there are...

While femtocells were virtually non-existent in 2006, and deployed by one operator in 2007, they will make up 61 percent of small cellular base station revenue by 2013, reports In-Stat. Microcells, picocells and femtocells provide indoor cell phone coverage in a cost-effective manner. “As mobile operators migrate from larger...
