RF/Microwave Circuit Design

Microwave Office circuit design software is used by leading manufacturers to accelerate product development of high-frequency electronics. The intuitive interface, innovative design automation, and powerful harmonic-balance circuit simulation ensure greater engineering productivity and accelerated design cycles. RF-aware layout, high-frequency models, design automation, and powerful HB simulator ensure greater engineering productivity and accelerate design cycles for today's most challenging applications.    

The Microwave Office Advantage

Best-in-class harmonic balance engine provides fast and rigorous convergence of highly nonlinear networks, addressing 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 and electromagnetic simulators provides in-situ parasitic extraction, design verification and standards-compliant communication test benches.

Features at a Glance

  • Comprehensive Libraries  Simulation models for discrete and IC-based, active and passive devices
  • APLAC – Proprietary multi-rate harmonic balance engine provides robust linear and nonlinear circuit simulation
  • EM Analysis – Fully-integrated circuit/electromagnetic co-simulation for design verification and in-situ extraction
  • Load Pull – State-of-the-art load-pull analysis and design support
  • Stability – Linear and nonlinear stability analysis
  • Synthesis – Impedance-matching and filter-synthesis wizards (options)  



Helping designers meet their amplifier bandwidth, efficiency, and linearity goals with advanced design automation and robust HB simulation for fast and accurate nonlinear analysis of RF/microwave circuits. Highly accurate semiconductor device/circuit element models and design support features empower RF amplifier designers with functionality to quickly bring products to market.

Filters / Passives

The iFilter™ filter design utility addresses all stages and types of filter development, from lumped-element or distributed filters to more complex multiplexed, high-power, and high-Q cavity filters. Passive networks such as couplers, combiners/dividers, and attenuators are simulated with a comprehensive distributed model library to aid component designers in meeting challenging size, cost, and time-to-market goals. 


Couples seamlessly with EM solvers to simulate antenna metrics such as gain, return loss, radiation efficiency, and currents, and to visualize 2D/3D far-field antenna patterns in support of antenna design, matching-circuit development, and integration into RF front-end electronics.


Delivers superior HB circuit simulation for the multi-tone, frequency-domain analysis required by designers of mixers and frequency converters commonly found in superheterodyne receivers.

The seamless integration of the Microwave Office and VSS software gave me more meaningful results because I was able to simulate my power amplifier circuit design’s response to the EDGE/GSM modulated input signal with one design platform. I used Microwave Office and VSS from circuit concept all the way through to product completion. I was exceptionally happy with the technical quality of the ACPR and EVM simulation results.
