The HEMT model in this article is applied by OMMIC D01PH. In this article we design a five circuit, the first two levels are designed for minimum noise and the last three for maximum gain design. The center frequency of this design is 35 GHz with 6 GHz bandwidth, gain is greater than 30dB and the noise figure is less than 3dB. This article describes a Ka-band low-noise amplifier design idea. In this idea we put up two options for the bias circuit design, one is drain supply by a single power and the other is dual-power supply for the drain and gate. We make circuit design and simulation for each program and the simulation results were analyzed and compared.
