Which RF range (for the AESA radar) and nm process range are you talking about for GaN transistors + IC et al.?
Let us establish those, then we can get to the nm range machines are available to Turkey (past and present).
It is nowhere near what large production commercial processors (fully silicon based) achieve.
The RF power density (and thus thermal consideration) of GaN is whole reason it need not get to those scales of say <14nm for IC chipset.
In fact nowhere close, I believe GaN IC's are in the 100nm area right now....maybe pushing to 80 these days....thermal considerations become far bigger criteria slowing this progress down.
This is anyway threshold stuff to push well past X, Ku K and Ka band stuff though into V (which has been passive only if incorporated in ESAs so far).
The chipset machines are not too difficult to acquire, you just need partnership with developed country that produces them....and more importantly the underlying RnD science and engg people to develop the process and application regarding them.
Being part of NATO has networked many things for TR military industrial complex for the appropriate machines and hardware regarding these years ago.
Turkey also has good relations with both Japan and South Korea.

Just quick search got me these interesting leads that shows evidence TR is gestating and developing capacity here:
