摘要：

This paper reports on a 0.2-8 GHz high dynamic range GaN MMIC LNA-PA which achieves sub-dB noise figure and a P1dB of 2 Wafts. The GaN MMIC utilizes a 0.2um AlGaN/GaN-SiC HEMT technology with an fT similar to 75 GHz. At high power bias (15V/400mA), the NMC amplifier achieves Sub-dB NF similar to 0.7-0.9 dB over a 2-8 GHz band. At low bias(12V, 200mA), the amplifier achieves similar to 0.5dB over the same band. Thi is believe to be the lowest NF reported for a multi-octave MMIC amplifier in the S- and C-band frequency range. In addition, the amplifier obtains ultra high linearity with an OIP3 of 43.2-46.5 dBm and P1dB of 32.8-33.2 dBm (2Watts) over a 2-6 GHz bandwidth. The PAE at P1dB is similar to 28.6-31%. The Psat is 34.2 dBm with 39% PAE @ 2 GHz. To our knowledge, this is the first report of a multi-octave MMIC amplifier with sub-dB NF and a Pout > 2 Watt.
