PA Simulation and Design Support
V15 of AWR software allows designers to optimize PA linearity performance through video band load-pull analysis of power
amplifiers (PAs) operating under two-tone excitations. Designers can plot intermodulation (IMD) and third-order intercept
point (IP3) results as a function of (F2-F1) impedance, directly investigating IMD products over swept input power. Load-pull
analysis also supports impedance tuning at the 4th and 5th harmonics as well as the ability to generate contours on rectan-
gular plots for enhanced visualization of performance versus load impedance.
Video-band load pull supports low-frequency impedance optimization to reduce IMD product (left) and loop gain envelope provides fast and
rigorous nonlinear stability analysis and optimization (right)
EM Simulation and Antennas
To enhance the speed and capacity of EM analysis for IC, package, and board structures, AWR AXIEM meshing and solver
technologies have undergone several key improvements, resulting in improved mesh quality for faster simulation run times
and the ability to solve larger problems with a reduced mesh. AWR Design Environment V15 software can now detect and
remove problematic mesh facets automatically with robust healing of high aspect ratio facets (HARF).
Improved meshing and EM solver tackles large structures, faster
