Optimizer is new intelligent tool for Vector Fields’ electromagnetic modeling and simulation software that will automatically find the best solution to a design problem. Optimizer automatically selects and manages multiple goal-seeking algorithms to eliminate the need for manual intervention and to make optimization feasible in virtually all design cases. Optimizer works in conjunction with the Opera electromagnetic design package, which is available in general-purpose form, or with solvers dedicated to specific electromagnetic applications. The tool automatically applies and dynamically manages the algorithms to eliminate the usual requirement to perform lots of time-consuming simulations.

Modelithics Inc. has released an enhanced version of its CLR Library™ of highly scalable, passive surface-mount component global models for Agilent-ADS. This upgrade adds several new models, including 01005-, 0201-, 0402- and 0603/0604-size capacitors and inductors from vendors such as AVX, Murata, Taiyo-Yuden, Coilcraft, Toko and TDK. In addition, the 5.0 release includes a new feature that will automatically update the layout geometry for pad-scalable models to match user-specified values for the pad dimension parameters. This significant upgrade will be available free of charge to all CLR Library (for ADS) customers currently under a Modelithics Platinum Maintenance contract. This update will be available for other supported simulators in the near future.

Guided Wave Technology’s Filter and Coupling Matrix Synthesis software facilitates synthesis of N+2 coupling matrices for Chebyshev bandpass-filtering functions, with arbitrary finite-position transmission zeroes. The software also facilitates coupling matrix synthesis through topology matrix definition. It gives a fast and accurate overview of insertion loss, isolation, group delay and coupling coefficients versus filter order, return loss and transmission zero positions. The software allows placement of complex transmission zeroes, which opens up for group delay shaping and analysis.

Agilent Technologies Inc. has released GoldenGate Plus for RFIC simulation, analysis and verification. Agilent’s GoldenGate Plus product line speeds the design of large-scale RFICs for wireless communication products. It combines the high-capacity GoldenGate simulator, acquired from Xpedion in 2006, with a customizable data display, electromagnetic (EM) simulation, and system-level design and simulation. The GoldenGate simulator is fully integrated into the Cadence Analog Design Environment. Its unique algorithms are optimized for the challenging demands of large and complex RFIC design, and enable full characterization of complete transceivers prior to tape-out.

MegaWave Corp. has applied a new absorbing boundary technique for the Flomerics MicroStripes 3D electromagnetic (EM) simulation solution that accelerates the design of low-profile and zero-profile ground antennas. In order to accurately model ground waves using electromagnetic simulation, the Earth normally needs to be modeled to at least three times the skin depth of the wave to allow space and time for the ground wave to be differentiated from the fields that propagate into the Earth that are ultimately dissipated in the dielectric losses. The new technique creates a boundary condition that absorbs the field propagating into the Earth model without disturbing the ground waves that contribute to the overall antenna radiation pattern.

Samsung Electro-Mechanics Co. Ltd. (SEMCO) has released a model library of its state-of-the-art, high-density, miniaturized, surface-mount multilayer ceramic chip capacitors (MLCC) for use with AWR’s Microwave Office® design suite. The Samsung/AWR MLCC library consists of hundreds of capacitor models, including high-frequency, high-capacitance, high-voltage, low profile, super small array and low inductance ceramic capacitors (LICC). The component models themselves utilize S-parameter data taken directly from the actual device characterization process, which in turn yields excellent accuracy of the capacitor’s electrical response within Microwave Office simulations (frequency- and time-domain). The Samsung MLCC library is free to AWR customers.
