DRDO has invested a lot of money in gallium nitride MMIC development projects and there are plans to set up a state of the art GaN foundry at IISc.

will greatly enhance the detection range (greater than 200km for a 1sqm RCS target). It also eliminates the requirement of a liquid coolant circulation based cooling system. Existing radars in IAF service use traveling wave tube amplifier and slotted waveguide antenna
The bandwidth of these radars is relatively narrow (600-800MHz). More advanced radars such as Uttam and EL/M-2052 have a much wider bandwidth (1-3GHz). A wideband radar using TSA radiating element may have a bandwidth no less than 5 GHz and an enhanced probability of detection
classification and it's much more difficult to jam. The associated wideband/multi-channel MMIC is however very complex and expensive. It is in an early development stage and the technology in question is futuristic. If this radar tech indeed goes to the AMCA,

+then the development period is perfectly aligned with the timeline of the aircraft being inducted into the IAF i.e beyond 2032.
