Its interesting that although GAN is in regular and fairly extensive use today, how Wolfspeed and QORVO have not released GAN models for public domain simulators. It is also interesting that public domain developers such as LTSPICE and QUCS seem to be not interested in implementing a proper GAN model for RF and/or Power electronics. This trend has limited the usage of GAN and both fabricators and users of GAN are suffering, It is about time some entrepreneurs ( University or industrial) develop these models for the public domain simulators and thereby give some relief to users who do not have Fort Knox in their back pockets to buy ADS or Microwave Office.
