This approach is especially suitable for high-frequency applications due to the loading effect in transistors connected in parallel. To the best of the authors' knowledge, this work demonstrates for the first time the implementation of the DS technique in GaN-based LNA MMIC. As a proof of concept, two single-stage 4.5-5.5 GHz LNA MMICs, with and without DS technique, are designed using FBH 250 nm GaN on SiC process, with a focus on improving linearity without additional power consumption. A two-tone measurement around 5 GHz shows a 6 dB output third-order intercept point (OIP3) improvement, from 38.7 dBm for a conventional LNA to 44.9 dBm for an LNA with DS. This leads to an improvement in the linearity figure of merit (LFOM = OIP3/Pdc) from 6.6 to 28.}, language = {en} }
