These systems require amplifiers with high power, wide bandwidth, and high efficiency to which Qorvo researchers have developed power amplifier MMICs utilizing the non-uniform distributed power amplifier (NDPA) approach. Showcasing impressive results, these NDPA MMICs (Figure 1) are designed for saturated operation. This requires accurate electromagnetic data up to the 5th-7th harmonic frequency, which results in a very large mesh/matrix. Because solving the entire structure was not practical, it was never attempted, but upon hearing about the nearly linear scaling in the AWR AXIEM planar EM simulator within the AWR Design Environment platform, Qorvo fellow Chuck Campbell elected to take the AXIEM challenge.
