19~21 GHz GaAs high linearity power amplifier MMIC
Published 2025-04-01Subjects: “…adaptive biasing circuit…”Based on a technology of 0.15 μm GaAs high electron mobility transistor (pHEMT), a 19~21 GHz high linearity power amplifier MMIC was demonstrated in this paper. In the scenario of signal transmission with high peak-to average power ratio(PAPR),the efficiency and linearity of power amplifier(PA)have...
