Bryan Sayler – Senior Vice-President and General Manager at ETS-Lindgren Test and Measurement Division talks about his company’s membership in the WiMAX Forum and discusses their new WiMAX™ RPT Test System.
Peter Krauss – Managing Director of Mician GmBH speaks with Richard Mumford about the development of EM simulation tools, their application in emerging markets and the importance of collaboration.
This month, Microwave Journal talks with Bryan Sayler, Senior Vice President and General Manager at ETS-Lindgren Test and Measurement Division, about his company’s membership in the WiMAX Forum. We also discuss the company's new WiMAX™ RPT Test System designed to provide detailed information on the radiated transmit and receive performance of wireless devices in an over-the-air environment. Sayler brings 20 years experience developing RF test solutions with ETS-Lindgren to his advisory role within the WiMAX Forum and its formalization of RPT measurement requirements. He received his BA degree from Southeastern University and his MBA degree from Baylor University.
The new R&S R-Line test chamber from Rohde & Schwarz combined with the R&S TS8996 test system delivers an EMI/EMS test performance and accuracy for wireless devices that is comparable to that of systems 10 times larger.
Tyco Electronics announced it has received a $2 M contract award from Raytheon Missile Systems to produce products for Raytheon’s precision-guided, long-range Excalibur artillery projectile. Tyco Electronics will produce M/A-COM telemetry transmitter modules, Global Positioning System (GPS) antennas and telemetry antennas to support Excalibur and contribute to the projectile’s...
Ansoft Corp. has released new versions of Nexxim®, the company's high-capacity circuit simulation software, and Ansoft Designer®, its integrated schematic and design management software. The products include new statistical analysis and transient simulation capabilities that allow engineers to rapidly simulate high-speed serial channel behavior. This eliminates prototype iterations that...
A miniaturized quarter-circular-slot UWB (QCS-UWB) antenna using field-pattern analysis of the circular-slot UWB prototype antenna is proposed. Even though the proposed antenna has only the quarter part of the prototype antenna it maintains UWB antenna characteristics. The measured gain of the miniaturized antenna from 3.0 GHz to 12.0 GHz is within -0.1 dBi ~ 1.6 dBi, which is comparable to the prototype antenna’s gain, -2.7 dBi ~ 3.1 dBi.
A four feeding microstrip antenna operating at 2.0 GHz and match to a 50Ω impedance designed using Agilent’s Advanced Design System (ADS) and Computer Simulation Technology (CST) simulation tools is presented.
Recent advances in Fresnel zone plate antenna technology, including sidelobe reduction and control over sidelobe location are explored, as well as the focusing resolution of Fresnel zone plate antennas for sub-wavelength focal distances.
The R&S HF907 double-ridged waveguide horn antenna from Rohde & Schwarz improves accuracy in EMI and EMS measurements. The unique, modified design of its housing ensures high and flat gain from 5 dBi to 14 dBi without any gain losses.
The R&S RFEX-Fast EMF measurement software from Rohde & Schwarz enables engineers and technicians to quickly and easily validate compliance with legally defined emission limits. Network operators, test houses, service providers, and regulatory authorities can all benefit from its efficiency and ease of use.
