We report a robust Q-band GaN MMIC LNA operating in the 42-47GHz frequency range using a 0.15 mum T-gate process. The measured noise figure of the MMIC is less than 3.1 dB over the band of interest and the NF has a minimum of 2.9 dB at a frequency of 45.5 GHz. The MMIC gain is between 19 and 20 dB across the band and the input return loss of the MMIC is less than -10 dB. The measured OIP3 of the MMIC...
We report robust GaN MMIC LNA operating over 4 GHz-6 GHz frequency range. An FET biased in common-drain configuration is used on the second stage of the MMIC to obtain good input return loss at the optimum noise match over the entire frequency range. The measured noise figure of the MMIC is less than 2 dB over the 4.5 GHz to 16 GHz frequency range and NF has a minimum of 1.45 dB at a frequency of...
