Abstract
GaN technology has shown improved characteristics at high power and high frequency conditions, playing a key opportunity in the space industry. In this way, this paper presents a GaN-based MMIC power amplifier (PA), designed for X-band space applications. The PA design consists of a single stage class-B and achieves 10.5 dB gain at 9 GHz and an output power of 32 dBm. It is verified that the MMIC can operate also as a rectifier, with a conversion efficiency of around 40 % for a CW input signal of 28 dBm at 8 GHz. Additionally, two-tone measurements are performed and compared to the CW ones.
