May 2008 Software Speeds Development Of Mixed-Technology PCBs A JOINTLY DEVELOPED solution is promising to significantly improve productivity for the design of RF circuits on printed circuit boards (PCBs). This integrated solution enables PCB mixedsignal designers (RF, analog, and digital) to concurrently design a PCB using Mentor Graphics’ Expedition Enterprise or Board Station XE flows. At the same time, the design is integrated with Agilent’s Advanced Design System (ADS) electronic-design-automation (EDA) software... — Nancy Friedrich April 2008 EM Simulator Models Acoustic/Electric Designs Simulating a high-frequency device before it is built can help avoid pitfalls in its design and manufacturing. Fortunately, engineers faced with predicting the behavior of RF and microwave circuits have a wide array of electromagnetic (EM) solvers to choose from, although selecting an optimum simulation tool should require consideration of some practical guidelines. There are several classes of solvers, with each best suited to a... — Marco Farina April 2008 Large-Signal Approach Yields Low-Noise VHF/UHF Oscillators Oscillator design for veryhigh- frequency (VHF) and ultra-high-frequency (UHF) applications has been well documented in books and journals. Most early work focused on frequency stability and, to a lesser extent, on efficiency and output signal quality. But with increasing use of advanced modulation formats in communications systems, and the growing need for oscillators with... — Ajay Kumar Poddar , et al. April 2008 Advanced Simulators Focus On EM Fields Electromagnetic (EM) simulation software is no longer a luxury but now an essential tool in any practical highfrequency design effort. The number of commercial programs has grown steadily over the years, providing RF/microwave designers with an unprecedented number of choices in EM simulators, including software for analysis of planar designs as well as full three-dimensional structures. Most of these EM tools link seamlessly to other... — Jack Browne March Analyze EM Parameters Of Slotted Tube Couplers This numerical method accounts for thickness effects in determining the coupling coefficient as well as the even-and odd-mode impedances for slotted tube couplers. Abdelhafid Lallam Assistant Professor of Physics University of Mascara, BP 305 Route de Mamounia 29000 Mascara, Algeria; (045) 80-41-68/69, FAX: (045) 80-41-64, e-mail: ab_lallam@yahoo.fr Nadia Benabdallah Physics Engineer ... — Yamina Bekri , et al. February CAE Firm Celebrates 20th Anniversary MARLBOROUGH, MA—This year, Flomerics (www.flomerics.com) celebrates its 20th anniversary as an independent company. According to the company’s founder, Dr. David Tatchell, this landmark is a testimony to the company’s high-integrity, people-oriented culture and its core concept of delivering engineering simulation software for use by designers and engineers rather than just full-time analysts and specialists. Flomerics ... — Nancy Friedrich January 2008 CST Acquires Flomerics' EM Business Line For software vendors, acquisitions usually offer a chance to enter new market areas and an immediate way to provide new services and products for customers. Through its acquisition of Flomerics’ (www.flomerics.com) electromagnetic (EM) simulation software business, for example, Computer Simulation Technology or CST (www.cst.com) gains considerable EM simulation capability while adding... — Nancy Friedrich December 2007 Software Tool Brings EM Technology To Forefront Jack Browne Technical Director Electromagnetic (EM) simulation software has evolved from a laboratory curiosity to a valuable modeling tool during the last decade. But many users still consider the technology as a "back-end" design tool, often applied as a way to check the results on "more trusted" S-parameter-based circuit simulators. To change that way of thinking, Applied Wave Research ... — Jack Browne December 2007 Simulating WiMAX System Performance Rapid growth of Wireless Interoperability Microwave Access (WiMAX) as a broadband wireless technology is expected due to increasing demand for convenient Internet access and highspeed data access. In order to construct wideband wireless systems such as WiMAX, however, effective modeling must be performed. In this report, wideband modeling was performed on key elements of a WiMAX system, notably the modulator, frequency upconverter, and... — Kostas Stefanou , et al.
