This paper presents high gain and too low noise figure low noise amplifier (LNA). To achieve high gain and low noise figure (NF), resistive feedback in conjunction with source degeneration is used. Also, for achieving high gain, this work is implemented with cascading two stages and for achieving low noise figure, InGaAs HEMT technology is used and Ku Band at 14 GHz LNA is designed for space application. Simulated results are NF of 0.76 dB, and gain of 30.67 dB. The less than −14 dB is achieved for return losses of input and output. The Stability Factor and Mu1 is greater than 4 at desired 14 GHz. The amplifier biasing V ds , I ds is 2V and 10 mA respectively are chosen. The Keysight Technology Advanced Design System is used for simulating all parameters. The LNA consumes low power of 300 mW from the simulated values.read more
