Abstract
We explore the benefits of continuum mode amplifier design using a graded GaN HEMT structure operating at a low drain bias of 5V to meet requirements of efficiency, linearity and bandwidth in 5G mobile networks. A significant increase in the available design space for high-efficiency is observed in the graded-channel device when compared to a conventional GaN HEMT, revealing the advantages of broad bandwidth, over and above improvement of 20-30 dB in linearity due to the intrinsic flat transconductance and linear gate capacitance characteristics of the graded device.
