Radiofrequency MEMS + CMOS. Matured Technology Ready for the Peak Hour Modern electronics need reconfigurable RF front ends that can share various protocols. These modules must have small size, low losses, high tuning range and low power consumption. These requirements can be met with reconfigurable MEMS controlled by CMOS chips. Present RF MEMS/CMOS chips that can replace FETs and HEMTs in RF systems are reviewed.
Direct Digital Modulation: Principles and Solutions Digital processing is increasingly used in blocks that previously could be realized only by analog technology. If before now digital signals were generated on IF recently arouses interest in the idea of direct digital modulation. What are the achievements in this advanced technology?

Ultrabroadband Devices. Classification and Application More then ten years ago at USA there was reached a decision of ultra wideband radiosystems legalization o the unlicensed basis. Legislative ultra wideband units operation was authorized in Russian Federation, Canada, Europe, Japan, South Korea, Taiwan and other countries. This article tells about ultra wideband devices that are at the market today and where they are used
Atmel’s SAM D – Cortex-M0+ MCUs: Optimal Performance/Energy Efficiency Today the most in demand MCUs and CPUs are Cortex core units. After many other producers Atmel in June 2013 announced a first series of an universal MCU SAM D20 on the Cortex-M0+ core basis.
Electric Power Meters. Module Construction, Low Production Cost Today there are more then ten home and foreign producers at the Russian electricity meters market. Under the fierce competition the successful advance and lifetime of a new product depends on its characteristics along with low production cost. This sets for the designers great challenges that can be solved only with the help of current development methods and technologies that determine the future devices.
Gowanda Electronics. In Pace with Technological Advances Gowanda Electronics is one of the major suppliers of components for OEMs. The primary applications of their products are high performance measurement equipment and instrumentation for military and aerospace systems, medical apparatus, business equipment. Company products designed for high performance applications are considered.
AXIe Measurement Systems. Test Evolution Corp. determination Some test equipment manufacturers produce devices supporting AXIe standard. The standard was adopted in 2010 and based on AdvancedTCA (ATCA) architecture with extensions for instrumentation and test equipment. One of the leading AXIe equipment manufacturers is Test Evolution Corp. This article describes products of the company.
Digital Verification Methods for Simulating mixed-signal SoCs in Synopsys VCS and CustomSim New generation SoCs contain more and more analog blocks. Analog blocks are also needed to work with several power supply, clock generation, DAC and ADC domains. To develop such SoCs a medium that combines analog and digital verification methods is necessary. Such capabilities provides mixed simulation technology Synopsys AMS.
Parabolic Dish Antennas calculation by Current Microwave CAD In the dimensions of current dish antennas for satellite communication and radioastronomy (from tens of centimeters to hundreds of meters) settle hundred and even more wave lengths. For large dish antennas radiation characteristics analyze and calculation methods of planar optics and geometrical theory of diffraction and also methods of physical optics and physical theory of diffraction are used
Lights off – Spot On The article considers advanced applications where high expectations are put on silicon carbide, an old material that was rediscovered.
Compact SAW RFID Tabs. Functionality Expansion A new RFID tab construction with an interdigital unidirectional coupler for decreasing tab’s dimensions was proposed and investigated. The coupler specific feature is the capability to shift surface acoustic waves from one acoustic channel to another one but in the opposite direction. It was experimentally shown that the couple’s attenuation was less then 1dB
EMBEDDED WORLD-2014 – Embedded Systems to the Full Extent At Nurтberg Feb.25–27 took place the 14 International Exhibition Embedded World, one of the main events in the world of embedded systems. There were demonstrated different electronic products: MCUs, FPLDs, displays, power supplies, single board computers and others. This article describes some systems that were presented by the leading world producers
Scaling came to the end of the road? Economics of scaling Today there is a big cause to study 28nm process versions that provide lower power consumption, higher yield and hence lower production costs then previous generation processes. From this it emerges that it is necessary to analyze various 28-nm technological processes value indicators to reach a right decision considering the next generation 20-nm technology.
Display Week 2014. Small Start of Big achievements For the first time a review of some of the most interesting design efforts that will be introduced at International SID Symposium at San-Diego July 1–6 2014 are reviewed. Special focus is on new flat panel displays versions and displays’ ergonomic.
