Abstract

In this paper, wideband MMIC LNA's were designed using low Q matching network. gains of 23.6~25.4dB $(24.5\pm0.9dB),$ noise figures of 0.9~2.8 dB were obtained from the designed wideband MMIC LNA in the frequency ranges of 1.2~2.8㎓. And, P1dB of 10.13 dBm, IP3 of 12.25 dB were obtained at the center frequency of 2 ㎓. A chip size of the designed wideband MMIC LNA is 1.4mm$\times$1.4mm.
