They are working on AESA for TF-X for one.
It's not just TFX. F-16 integration is also planned ahead. In addition, testing of the marine version with CAFRAD continues. The actual firing tests were successful. Aselsan is one of the few institutions in the world that can successfully produce the GaN based T/R modules.
GaN (GaN-on-SiC) based RF / microwave transistor and microwave integrated circuits (MMIC) grown on Silicon Carbide; It provides great advantages in size, weight, power and reliability metrics at system level due to its power per field, easier adaptability, refraction voltage and radiation resistance in space applications.
Also Turkey is testing its own Silicon Germanium (SiGe) BiCMOS Technologies. This will integrate SiGe-based Bipolar Transistors (HBT) and Silicon-based CMOS processes, and provide high-performance RF and control circuits to work together.
These studies have been officially carried out since 2013 together with Aselsan, TÜBİTAK-BİLGEM's Semiconductor Technologies Research Laboratory (YİTAL) and Bahçeşehir University.
ASELSAN also designs and manufactures technologically critical microwave modules and components in dedicated special areas, for years. The design and production activities consist of high performance transmitter and transmitter/receiver modules, front-end modules, frequency converters, power amplifier modules, digital frequency discriminators (DFD), logarithmic video amplifiers (DLVA), filters, monolithic microwave integrated circuits (MMIC), thin-film based components for the mission critical radar, electronic warfare (EW), intelligence, and satellite systems. Microwave module production capability is extended and reinforced with thin film and microwave multilayer packaging technologies.
