Communication System design and verification
Ansoft Designer® allows engineers to apply flexible RF and baseband behavioral and electrical models for rapid system architecture development, creating link budgets and specifying circuit requirements. Behavioral models include impedance specification for accurate reporting of mismatch loss, linear and non-linear behavior, circuit (transistor-level) and EM co-simulation for system-level design verification. Ansoft Designer quickly simulates entire analog/digital transmitter-to-receiver chains, including propagation effects, enabling engineers to make key decisions and tradeoffs up front to speed time-to-market and to better manage costs.

High-performance analog/RF IC design and verification
For high-performance analog/RFIC design and verification, Ansoft Designer complements existing IC design capture and advanced package layout tools with its built-in planar electromagnetic solvers and dynamic, parameterized co-simulation with HFSS and Nexxim. Engineers can create accurate models of on-chip passives and board/package interconnects, combine them with detailed analog circuits and simulate the true interactions between active non-linear devices and passive parasitics associated with packaging, substrate coupling, vias, bond wires, and other IC interconnects.

High-performance RF & mW Board Design
Increasing component densities and the number of board layers make board characterization and overall system/sub-system verification a greater challenge for RF designers. Neglecting proximity effects can lead to resonant frequency shifts, spurious oscillations, and a host of problems related to unexpected signal coupling. Ansoft Designer provides the powerful handshaking between HFSS and Nexxim's high-capacity harmonic balance and transient circuit simulation to ensure optimum design of distributed and discrete surface-mount RF PCB circuits, optimum VSWR/insertion loss between packaged ICs as well as more accurate predictions of non-linear performance metrics such as IMD, spurious and harmonic products, ACPR, EVM, MER, and power added efficiency.

Antenna and Passive RF component design
Ansoft Designer® and HFSS™ provide dynamic parameterized co-simulation to simulate electrical models (S-, Y-, Z-parameters) for arbitrary 3D structures. Additionally Ansoft Designer can combine multiple HFSS 3D structures into larger networks for simulation. Using Ansoft Designer's built-in planar EM simulator or other dynamically linked Ansoft EM simulators, engineers can develop antennas, phased arrays, filters, coupler, circulators, spiral inductors and other passive microwave elements. Ansoft Designer's 3D planar EM capabilities can analyze highly complex or electrically large geometries, complex stack-ups, and "thick-metal" geometries. For full 3D structures, Ansoft Designer compliments HFSS with unparalleled integration.
