Modelithics now offers its customers nonlinear X-parameter measurement and modeling services. This state-of-the-art technology is enabled through use of Agilent Technologies’ PNA-X Series Nonlinear Vector Network Analyzer (NVNA) and provides circuit board designers with mathematically correct extensions of S-parameters for large-signal conditions for devices such as amplifiers, mixers and...

Texas Instruments Inc. (TI) introduced the industry’s first Class H VDSL line driver in full production. Compared to Class AB alternatives, the gated, dual-port THS6226 consumes 47 percent less power, a critical requirement for the high-density VDSL applications used in high-speed broadband networks. And by offering a digitally adjustable...

Engineers throughout the world are being asked to design products more quickly, with fewer iterations and using an ever broadening range of technologies requiring analog, RF, power and mixed-signal expertise. Analog Devices Inc. , a global leader in high-performance semiconductors for signal-processing applications, is helping engineers save weeks of...

Skylogic , the broadband subsidiary of Eutelsat Communications, and Sat Internet Services GmbH have sealed a distribution agreement for broadband services using the powerful KA-SAT High Throughput Satellite. According to figures published by industry analysts of TÜV Rheinland, approximately 770,000 German homes have no broadband access, with up to...

Cadence Design Systems, Inc. announced major enhancements to its Virtuoso®-based custom/analog flow, boosting productivity across the entire flow from initial design specification to final GDSII and for process nodes down to 20 nanometers. The expanded custom/analog flow--spanning design, implementation, and verification--includes methodology improvements to help designers manage design parasitics,...

The coaxial to rectangular waveguide transition is one of the most important devices used in microwave and millimeter-wave circuits. Especially at millimeter-waves, a waveguide-to-coaxial adapter is one of the most often used components for efficient electromagnetic wave transmission and high power handling. Although many types of adapters are available...

The emergence of new wireless standards and the growing adoption of wireless radios in the consumer world have created new RF test challenges for engineers. With consumer devices using more radios and engineers performing more RF measurements than ever before, it has become increasingly clear to the industry that...

Multiple-In, Multiple-Out (MIMO) antenna techniques promise to deliver exceptionally high data rates over new wireless technologies such as LTE and LTE-Advanced. However, the increase in attainable data rates brought about by MIMO technology is based on taking advantage of several channel characteristics that were inconsequential to legacy technologies. These...

To characterize Global Navigation Satellite System (GNSS) receivers, a number of typical tests are used. These tests check how quickly a receiver can fix its position after it is switched on, or how accurately the calculated position matches its actual position. Users normally perform a complete series of tests...
