This paper demonstrates a broadband GaN HEMT Low Noise Amplifier (LNA) with high linearity. The proposed two-stage LNA employs a low noise HEMT on the first stage and a high power HEMT on the second stage. To realize a broadband and high flat-gain performances, each matching circuit of the GaN LNA were designed to perform different frequency characteristics, resulting in high flat-gain performance finally. The fabricated GaN LNA using UMS 0.25 um GaN HEMTs achieved a gain of 21 dB 賊 2 dB and a NF of 2.0 dB 賊 0.45 dB in 0.8 GHz to 2.2 GHz. The input P1dB and the output IP3 of the LNA realize 7 dBm and 43 dBm, respectively. |
