Dear Electronics Marketer,

Selling solutions always involves adding value and your advertising message should be specific as to how this is achieved.

The August issue of RF Design and the supplement, Defense Electronics offers you a strong editorial environment to get your "solution " message to your most strategic customer — the loyal design engineering audience of  RF Design.

The military has changed dramatically over the past decade. Desert Storm was an air war and Iraq is fought on the ground against insurgency. Advanced technology such as global positioning systems that were developed for military aviation age are used to support ground troops. The August issue of Defense Electronics delves deeper into how they affect land and sea warfare by examining the latest developments in electronics and component design. If you are a marketer selling components targeting the military,  the good news is, that it is not too late to get your ad in the August issue of  Defense Electronics.

Also, take a look below at  RF Design's regular August lineup which examines Microwave/mm Wave Technologies, Broadband Technologies, Passive Components and Test and Measurement  through four mulitfaceceted articles.

Here are two golden opportunities, August RF Design and August Defense Electronics, to reach the RF Design Engineer with a solution, at the very time they are sorting out the critical issues facing these technologies.

Best regards,

Microwave/mm Wave Technologies
Pushing for 0 dB measurement error with calibration and temperature-compensation techniques

Applications requiring high power transmission are dramatically affected by even by the smallest margin of RF power detection error.  While ever-improving RF detector technology offers solutions for better accuracy, new applications continue to emerge and push the performance envelope.  The physical limit for RF power measurement is an uncertainty of 0 dB, and the goal, of course, is to meet that limit.  In this article, Carlos Calvo, Analog Devices, Inc., explores calibration and temperature-compensation techniques implemented in RF power management systems to reduce the measurement error.
 
Broadband Technologies
Harnessing the potential of powerline communications using HomePlug AV standard

With multiple outlets in every room, power lines are the most pervasive wires within the home. The use of this wiring for networking or communications, or powerline communications (PLC),  can go a long way in solving the home networking problem. PLC systems based on the HomePlug 1.0 standard are widely available in both North America and Europe. While HomePlug 1.0 is adequate for applications like web browsing, it cannot support multimedia applications, such as audio/video streaming and multi-player gaming, as these applications require much higher bandwidths as well as other stringent Quality of Service (QoS) guarantees. The HomePlug Powerline Alliance has recently released a new generation of HomePlug Standard, HomePlug AV, which is intended to support these emerging multimedia applications.

Srinivas Katar and Manjunath Drishnam, Intellon Corp., and Richard Newman and Haniph Latchman, University of Florida, Gainesville, Florida, discuss the challenges posed by powerline channels and how the HomePlug AV standard overcomes them. A brief description of the channel and noise characteristics is followed by an overview of the various salient features of the HomePlug AV PHY and MAC layers. Various novel design aspects that enable optimal adaptation under harsh powerline channel conditions are emphasized. HomePlug AV’s performance in field tests are provided.

Passive Components
Exploring the last frontier in the electromagnetics spectrum

The least-explored region of the electromagnetic spectrum consists of terahertz waves, which at 100 GHz to 10 THz fall between microwaves and infrared light. Only in recent years has the development of suitable waveguides for the technical maturation and widespread commercialization of T-ray technology started. Jason Deibel, Mittleman Terhertz Rsearch Group, Rice University, will discuss how researcher at Rice University have made important discoveries in this regard and are using mathematical modeling to study how their approach to waveguides works and how best to connect these waveguides to antennas and other system components.

Test & Measurement
Accelerated testing lifts the bar on product integrity

Highly accelerated life testing (HALT) and highly accelerated stress screening (HASS) are recognized as the fastest and most effective new standards for design verification and testing (DVT) and production screenings.  However, now the impact of these new testing methods is starting to reach all the way up into the boardroom to awaken C-level executives.  Besides discussing set-up and running these test systems, AualMark Corp., Denver, Colorado, shows how HASS and HALT can expose weak links in any product so that problems can be fixed early on before they become expensive field issues.

Radars/Surveillance
High-resolution radar system modeling with MATLAB/Simulink

 Although, modeling is a cost-effective way to create “proof-of-concept” results for novel radar architectures, they are difficult to implement due to  considerable number of variables and conditions to be taken into account. With new advances in modeling software and computer speeds, modeling and  simulation are becoming more attractive. In this article, author, Dmitriy Garmatyuk, Assistant Professor, Department of Electronics and Computer Engineering, Miami University, Oxfor, OH, shows that simulating the performance of high-resolution imaging radar system is achievable using simulation tools like MATLAB/Simulink. It uses Simulink’s large number of pre-made blocks to model high-resolution radar system such as the synthetic aperture radar (SAR).

Networking
New opportunity for real-time, pervasive data

This article explores the evolution from data networks to pervasive data.  With pervasive data, all information is available anytime at any place, without consideration of its origin. Stan Schneider, Real Time Innovations, Inc., offers a high-level, practical view of the state of distributed data transport, storage, and management.  It starts with the basic state of the art of real-time networking middleware, addresses the tough performance issues, and finally develops a vision for the pervasive-information future.

Software Radio
JTRS airborne antenna for subsonic aircraft, ship, and vehicular applications

Based on a universal modernization program, the Joint Tactical Radio System (JTRS) is to be used by all branches of the military to communicate using a single type of radio.  This requires a single antenna operating over the full JTRS band of frequencies. Author Joseph Jahoda, CTO and Founder, Astron Wireless Technologies, Inc, discusses a proprietary high, efficient, sensitive, accurate (HESA) technology that provides a flexible configuration of multiple antenna elements in a small form factor.  It implements various elements and their associated electronic components such as ferrite and dielectric loading elements; bandpass/multiplexer circuitry; and propriety variants of conventional antenna configurations, resulting in a more accurate, sensitive and efficient antenna.
