AWR’s AXIEM 3D Planar Electromagnetic (EM) Solver Enables TriQuint Semiconductor to Solve Entire Monolithic Microwave Integrated Circuit (MMIC)


Click to visit the Applied Wave Research websiteAWR - TriQuintEl Segundo, CA — December 10, 2009 — The Story: TriQuint Semiconductor has used AXIEM software to simulate an entire MMIC non-uniform distributed power amplifier (NDPA) on a quad-core PC with 4 Gbytes of RAM and a 32-bit operating system. It is first time the company has been able to electromagnetically simulate an entire structure of this size on a desktop PC.

AWR AXIEM software simulation for TriQuint MMICElectronic warfare (EW) systems require MMIC amplifiers that deliver high power over broad bandwidths with high efficiency, for which TriQuint’s NDPA approach is extremely well suited. However, designing these complex devices requires accurate EM data up to the fifth to seventh harmonic frequency, which results in a very large mesh/matrix of up to 32 ports and 30,000 unknowns. As a result, solving the entire structure has not been practical using available EM solvers.

However, AXIEM’s near-linear scaling allowed TriQuint to simulate the entire NDPA MMIC from DC to 120 GHz in under 2 minutes per frequency. The achievement was made possible by AXIEM’s shape pre-processor and hybrid adaptive meshing algorithms, which decreased the final mesh size to just over 6,000 unknowns. The MMIC demonstrates saturated RF output power of 9 to 15 W over a broad frequency range of 1.5 and 17 GHz with power-added efficiency greater than 20%.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
