Abstract
Trend on high-power GaN(Gallium Nitride) SSPA(Solid-State Power Amplifier) and its availability in miniature radar systems are presented. There are numerous studies on high-power GaN devices since they have some characteristics of high-breakdown voltage, high power density, and high-temperature stability. Recent scaled GaN technology makes it possible to apply it in SSPAs for W- and G-band applications, with increasing its maximum frequency. In addition, it leads to downsizing and power-efficiency improvement of SSPAs, which means that GaN SSPAs can be available in miniature radar systems. This study also shows radar performance and comparison in the case of using such SSPAs at three frequency bands of Ku, Ka, and W. Finally, we demonstrate prospects of scaled GaN SSPAs in future miniature radar systems.
