Oh Dear!
So these are your papers and articles?
First is a product data sheet of a Microwave Power Module based on GaN. It is not even a TRM of a AESA. FYI Here is a basic block diagram of a T/R M.
What you have here is only the power amp portion of this device. It is not even a complete T/R Module.
Second is a news article about how US is getting worried about China getting GaN technology. Sure!
Rest are all research papers in various subjects from Electronic system design, DBDP, etc etc. You didn't even care to point out how they are related to GaN T/R Modules! Just pure spam.
