Abstract
In this paper, a low noise amplifier(LNA) in a receiver of a Low Noise Block Down Converter (LNB) for direct broadcasting service(DBS) is implemented using GaAs HEMT. The 2-stage LNA is designed for the bandwidth of 11.7GHz - 12.2GHz. The result of a simulation of the LNA using Advanced Design System(ADS) shows that the noise figure is less than 1.4dB, the gain is greater than 23dB and the flatness is 1dB in the bandwidth of 11.7 to 12.2GHz.
