Hello Glefdar, I think you know the answer to the question you are asking. It is very unlikely AMPG has some new MMIC technology. If you followed Amplitech's press releases you would see so many lets be nice and call them PR exaggerations. In my opinion these press releases were just to get investors to give them money. So they can take raises and bonuses.
If you look at the AMPG LNA it looks like a 20-30 year old product. They are making amplifiers a very old way using discrete chips. This is a very slow costly way to make amplifiers. The market has changed a lot in 20 years. Now you can purchase MMIC's in plastic surface mount packages from $5 to $100. These are large US companies like Qorvo, Skyworks, MACOM, Analog Devices. It is very unlikely AMPG can enter this market
AMPG is stuck in bad place where their LNA's are old technology and no longer competitive in price or performance. They are living off investors giving them money.
