Abstract :
This article presents a 4-6GHz power amplifier in a 0.25μm GaN integrated technology from UMS foundry. Two unit power cells are combined to increase output power. A new power combiner based on a stacked balun is presented. It has the advantage of occupying a much smaller area than a conventional one. The measured circuit exhibits a peak output power of 37 dBm together with a peak PAE of 47% at 4GHz.
