Recent advances in space mapping technique modeling GaN HEMT

Gallium nitride (GaN) HEMT has board application prospect for 5G wireless communication systems. This paper reviews the recent advance in space mapping technique for GaN HEMT modeling technique. A novel decomposed-based space mapping technique is discussed. This method is a systematic modeling approach with fast developing speed. A 2×350 µm GaN HEMT device are used as an example.
