Abstract: | A 900MHz Low Noise Amplifier (LNA) is present in this paper. Using new method of optimization,it can achieve very low noise with power matched. The low noise amplifier can achieve 0.2dB noise factor and 20dB power gain with only 3.4mA current consumption, and the isolation and linearity are also very well. |
