RF Circuit Simulation Professional 2025

RF Circuit Simulation Professional (previously called RFPro Circuit) revamps circuit simulation and optimization technology for efficient and accurate design of the most challenging RF-microwave-mmWave circuits, RFICs and RF 3D Heterogenous Integrated (3DHI) modules for 5G/6G, wireless, radar, and defense-aerospace applications.

Figure 3a. RF Circuit Simulation Professional advanced multi-domain circuit simulation, optimization, and visualization capabilities are accessible from Keysight ADS, Cadence Virtuoso, and Synopsys Custom Compiler design platforms.

Figure 3b. RF Circuit Simulation Professional offers the industry's first Nonlinear Stability Margin simulation and optimization to maximize amplifier stability. Unlike traditional binary stable-or-unstable decision results, RF Circuit Simulation Professional stability margin analysis indicates the amount of instability risk, so that optimization can be applied to minimize it.

Multi-Domain RF Circuit Simulation Technologies

• RF Circuit Simulation Professional offers multi-domain circuit simulation algorithms to thoroughly characterize the multi-spec requirements that a design must simultaneously satisfy, e.g., efficiency, error vector magnitude (EVM), adjacent channel leakage ratio (ACLR), stability, gain, output power, and wireless 5G/6G standards compliance.
• RF Circuit Simulation Professional’ multiple circuit simulation algorithms operate across multiple domains (frequency, envelope-transient, linear, nonlinear, stability, electrothermal, system and measurement) for thorough characterization to satisfy multi-spec design requirements (see Figure 3a).
• Multi-domain simulations can be customized (e.g., multi-dimensional sweeps), sequenced and saved as workflows to ensure all required performance specs are consistently analyzed thoroughly.
• RF Circuit Simulation Professional circuit simulation can be accelerated by 16x through parallel runs on available compute resources. 
• Unique, state-of-the-art simulation algorithms with superior convergence and speed:
  • Error vector magnitude (EVM) with digital RF modulated signal excitation.
  • Breakthrough Envelope-Transient simulator for modulated signal excitation.
  • Fast Envelope with memory effects under modulated signal excitation.
  • Winslow's nonlinear stability replaces 14 traditional stability analyses (see Figure 3b).
  • Unrivaled nonlinear Harmonic Balance steady state simulator.
• Multi-physics design with other Keysight simulators:
  • EM-circuit cosimulation with RFPro FEM and 3D planar Method of Moments.
  • Electrothermal (ETH) to account for dynamic and device thermal effects.
  • System-circuit co-design with Virtual Test Benches (VTB) for standards compliance.
• Wide foundry PDK support for RFIC, MMIC and 3DHI RF module designs and successful tapeouts.
