Simulate your design with authentic 5G modulation and EVM measurements

Designing robust 5G power amplifiers for the real world requires simulating the effects of RF coupling and electro-thermal contamination. Circuit simulations must also generate authentic 5G modulation over a sufficiently wide bandwidth, which sets up crucial stability and load-pull analysis for achieving 5G power amplifier (PA) performance expectations. Simulating 5G PA designs at the component and system levels with authentic modulation and high-fidelity behavioral models increases predictability, lowers risk, and shrinks schedules. The millimeter-wave (mmWave) design engineer uses a comprehensive three-step RF electronic design automation (EDA) circuit simulation workflow for improved 5G PA predictability.

Multi-technology placement automatically inserts 5G PAs, with their physical and behavioral modeling characteristics, into dense structures ready for electromagnetic (EM) simulation. High-fidelity EM / circuit co-simulation with authentic modulation over a sufficiently wide bandwidth sets up crucial stability and load-pull analysis for achieving 5G PA performance expectations. Iterative thermal, error vector magnitude (EVM), and predistortion analysis expose cross-domain effects, discovering hidden weaknesses and protecting against added costs.
