Abstract: An X band broadband low noise amplifier (LNA) is presented. This amplifier, using NEC’s HJFET NE3210S01, had a microstrip stub matching structure and a two-stage topology. ADS was used as a tool to design, optimize and simulate. The designed amplifier exhibited broadband operation from 10GHz-13GHz with noise figure less than 2dB, Gain 21.5dB±1dB and SWR less than 1.8.
