RF/Microwave Circuit Design

Cadence® Microwave Office® circuit design software is used by leading manufacturers to develop high-frequency electronics. RF-aware layout, high-frequency models, and a powerful harmonic balance (HB) simulator ensure accurate and fast simulation results for first-pass success. The intuitive interface, innovative design automation, and design-assist features promote optimum engineering productivity and accelerate the development of RF/microwave IP across monolithic microwave IC (MMIC), RF PCB, and module technologies as standalone components or integrated within complex multi-technology systems.

Key Benefits


The best-in-class HB engine provides fast and rigorous convergence of highly nonlinear networks to address RF/microwave circuits with large transistor counts and/or harmonic content


Design automation, an intuitive interface, and scripting/customization supports all phases of product development in less time


Co-simulation with system, electromagnetic (EM), and mutliphysics simulators provides in-situ parasitic extraction, design verification, thermal analysis, and standards-compliant communication testbenches
