Abstract

In this paper, a wideband MMIC LNA was designed using low Q matching network. Gains of 9.8~12.2 ㏈, and noise figures of 1.7~2.1 ㏈ were obtained from the fabricated wideband MMIC LNA in the frequency ranges of 1.5~2.5㎓. And maximum output power of 10.83 ㏈m were obtained at the center frequency of 2 ㎓. The chip size of the fabricated wideband MMIC low noise amplifier is 1.4 mm$\times$1.4 mm.
