초록
In this paper, a low noise amplifier (LNA) in receiver of Low Noise Block Down Converter (LNB) for direct broadcasting service (DBS) is implemented by using GaAs HEMT The LNA is designed for operation between 10.7GHz-12.7GHz. The LNA consists of input, output matching circuits, DC-blocks and RF-chokes. The result of simulation of the LNA shows that a noise figure is less than 1.4dB and a gain is gloater than 9.2dB in the bandwidth of 10.7 to 12.7GHz with good flatness of 0. ldB
