MMIC Design
MMIC design at millimeter-wave frequencies can be easily accomplished using Ansoft's MMIC design methodology. This highly accurate MMIC design methodology incorporates rigorous 3D and planar electromagnetic simulation required for RF characterization with traditional system and circuit simulation techniques and validated device models.Electromagnetic based simulation is used for characterization of passive elements and circuit simulation is used for RF circuit design and optimization. Model library development is accomplished using optimized netlist fragments for active and lumped-element passive models. For distributed elements, users can choose between analytical models built into Nexxim® or planar EM generated models. Planar EM can simulate very complex structures, allowing designers to characterize the entire layout of MMIC circuits. HFSS can be used to examine structures that are not strictly planar and can perform packaging analysis making it possible to characterize all parasitic effects associated with millimeter-wave packaging. Development of this solution is valuable for emerging applications of millimeter-waves for very high-speed networking, digital communications, collision avoidance radar, and automatic cruise control systems, all of which benefit from the lower cost solution that integration provides. Featured Products Nexxim®
Nexxim® is an advanced, frequency- and time-domain circuit simulator for engineers designing the next generation of high- performance DigitalRF CMOS ICs, GaAs/SiGe RFICs, SIP/SOC packages, power delivery systems and gigabit computer and communication backplanes. Dynamic, parameterized co-simulation with HFSS™ and Ansoft Designer® enables Nexxim to combine transistor-level detail for complex and highly nonlinear circuits with full-wave S-parameter models of the interconnect to provide the most accurate simulation capability for signal-integrity analysis and RF design. Ansoft Designer®
Ansoft Designer® provides an integrated schematic and design management front-end for complex analog, RF and mixed-signal applications. By leveraging advanced electromagnetic field simulators dynamically linked to powerful circuit and system simulation, Ansoft Designer enables engineers to design, optimize, and validate component, circuit, and system performance long before building a prototype in hardware. HFSS™
HFSS™ is the industry-standard software for S-parameter, Full-Wave SPICE™ extraction, and 3D electromagnetic field simulation of high-frequency and high-speed components. Engineers rely on the accuracy, capacity, and performance of HFSS to design on-chip embedded passives, IC packages, PCB interconnects, antennas, RF/microwave components, and biomedical devices. |
