Power density of the new communications systems supporting the networked battlefield can be four times lower than that of the AM/FM radios they replace due to the use of advanced modulation techniques to improve data throughput of Net-Centric communications systems. These software-defined radios must operate over wide transmit bandwidths,...

An ultra high resolution radar is one of many promising areas of UWB applications because of its inherent nature of ultra wide bandwidth.1 In theory, UWB radar could achieve the ultra high range resolution of up to 2 cm if a single antenna could cover the whole UWB frequency...

Holzworth has released a product line of ultra low phase noise, multi-channel CW sources that incorporate up to eight independently tunable channels inside a single 1U high housing. One example is the HS3008A, 3 GHz RF synthesizer, which is capable of tuning frequencies from 8 MHz to 3 GHz...

Phase stability with respect to temperature has a direct impact on system performance and is therefore an important characteristic for high frequency components and subassemblies. Enhanced phase tracking with temperature translates into lower residual noise and reduced system uncertainties. Cable assemblies interconnecting critical high frequency signal paths will also...

AR’s Orange Book of Knowledge The third edition of AR’s “Orange Book of Knowledge” is now available. The book contains articles and application notes on a wide range of topics and applications, including “Custom Pulses Made Easy” to a reference guide for coaxial connectors and cables. Contact your local...

Herley Industries Inc. announced that its Herley New England division in Woburn, MA has received an award valued at approximately $16.4 M from a major US prime contractor to manufacture a variety of multi-function integrated microwave assemblies (IMA) for a US Navy electronic attack aircraft. Richard F. Poirier, CEO...

Remcom announced that its XStream® GPU acceleration now provides the capacity to solve electromagnetic simulation problems up to 300 times faster than a modern 64-bit CPU. In addition, Remcom announced this updated version of XStream will now be bundled at no additional cost with XFdtd Release 7.0 (XF7), the...

The Strategy Analytics annual forecast, “Markets for SI GaAs Epitaxial Substrates: 2008-2013,” covering the semi-insulating (SI) GaAs (gallium arsenide) epitaxial substrate market, concludes that the 2008 SI GaAs epitaxial substrate market grew 22 percent year-on-year, but projects a flat-to-negative market in 2009. Growth is forecast to return in 2010,...

Elcom Technologies Inc. announced it has been awarded contracts totaling $1 M for the manufacture of synthesizers and oscillators used in UAV and other airborne applications. Elcom’s RS series have been integrated into ECM, ESM, SAR, FCS platforms by both foreign and domestic manufacturers. Elcom’s custom modular microwave frequency...

AR RF/Microwave Instrumentation has introduced a family of new “S” solid-state series amplifiers that are more compact, more efficient and more powerful than previous models. The new “S” Series includes the following models (all cover the 0.8 to 4.2 GHz frequency range): Model 15S1G4 (15 W CW) Model 30S1G4...
