ABSTRACT:
A low-noise amplifier is provided according to the present invention. The low-noise amplifier includes a first amplifier stage, a second amplifier stage, a third amplifier stage, an input matching network, inter-stage matching networks, and an output matching network. The impedance of the input matching network and the input impedance of the first amplifier stage are conjugate matched, thereby decreasing system power consumption and noise factor. The system gain is enhanced by cascading three stages of amplifiers.
