The size of the antenna for a given application does not depend purely on the technology, but on the laws of physics where the antenna size with respect to the wavelength has the predominant influence on the radiation characteristics. With modern day communication devices becoming smaller and lighter, demand...

The idea of the "Software-Defined Radio" (SDR) has been circulating in industry and academia for almost 20 years, the term having been coined by Joe Mitola in a 1992 paper. 1 Since that time, many commercial and defense-oriented radio SDR products have been developed and released, most using basic...

Interference affecting RF signals is a familiar problem for development engineers working in the field of RF engineering. It may be caused by sporadic or brief events within the frequency domain, the spectral behavior of signal sources during frequency switching, or by digital circuits. Identifying the causes behind problems...

As the demand for energy efficiency increases, more electronics are being designed with switching regulators in place of linear regulators. Power systems with multiple switching regulators are becoming commonplace; as the number of regulators increases, the impact of electromagnetic interference (EMI) also grows. One of the simplest, most cost-effective...

Online marketing has been the buzz for many years now. Websites, webinars, whitepapers, Twitter, Youtube, Facebook, LinkedIn. I could go on. And at MWJ, we embrace the web and all that it offers for information gathering, networking and lead generation. It’s a vital component of any integrated marketing program....

The Boeing Co. and Northrop Grumman Corp. announced a strategic partnership in pursuing the competitive development and sustainment contract for future work on the Ground-based Midcourse Defense (GMD) system for the US Missile Defense Agency. "Boeing takes great pride in supporting the Missile Defense Agency on GMD, providing 24/7/365...

ThalesRaytheonSystems has been awarded a $21.8 M contract by the US Army to upgrade multiple AN/MPQ-64 Sentinel air defense radar systems. This award is an option to the existing upgrade contract originally awarded in June 2007. The contract will upgrade the US Army Sentinel radar transmitters, receivers and exciters,...

Lockheed Martin has delivered the first satellite in the Advanced Extremely High Frequency (AEHF) program to Cape Canaveral Air Force Station, FL, where it will be prepared for a July 30 liftoff aboard an Atlas V launch vehicle. The AEHF system will provide the US military and national leaders...

A group of 15 leading telecommunications service providers, component and infrastructure vendors, and academic institutions have launched Energy Aware Radio and Network Technologies (EARTH), a consortium whose goal is to achieve a 50 percent reduction in the energy consumption of 4G mobile wireless communication networks within the next two-and-a-half...

ETSI and NGMN have announced the creation of the ETSI Industry Specification Group on Open Radio equipment Interface (ISG ORI) that will specify an open interoperable interface for radio equipment in distributed mobile cellular base stations--GSM, UMTS and LTE. ISG ORI is a direct result of requirement work undertaken...
