Pushing the Limits of High Frequency Applications with Gallium Nitride HEMTs on Substrates
Pradyot GaN HEMT paper.png

Palacios Group researchers led by Pradyot Yadav published their first report of an RF HEMT on an engineered substrate and showed potential for further development of the proposed transistor for high-frequency applications. According to the authors, given the promising RF performance of fT/fmax=48/115 GHz and the availability of large diameter (8 in.) substrates, GaN HEMTs on engineered substrates have strong potential for use in applications such as 6G communication (W–G bands) and radio astronomy.
