“…Recent studies have demonstrated different realization forms of power amplifier MMICs for K-band transmitters, such as the 21-23 GHz GaN Doherty PA, 1 linear PAs, 2-3 and 18.5-24 GHz GaN on Si, GaN on SiC MMIC PA, 4 and a large number of GaAs MMIC PAs with different gate length processes. [5][6][7][8] In these studies, most of the MMIC designs are produced using a conventional design procedure and only consider the matching from a certain point of view, such as high efficiency or broadband. In this paper, an improved MN design procedure for MMIC PA capable of covering the entire downlink operating frequency band is proposed.…”
