A Ku-band High Gain 40 W GaN HPA MMIC for Satellite Systems in a 0.25- μm GaN Technology

This study focuses on the design and validation of an internally matched high-power amplifier monolithic microwave integrated circuit (MMIC) for Ku-band solid-state power amplifier (SSPA) system integration. The designed MMIC exhibits sufficient power gain and output power characteristics, making it suitable for SSPA applications. The MMIC offers a compact and cost-effective SSPA configuration by reducing the number of components, such as gain blocks, isolators, and power combiners. The results show a performance of more than 40 W output power with a considerably high saturated power gain (greater than 22 dB) over the entire band (15.25–16.25 GHz).
