Abstract

Wireless LAN technology is one of the needed facilities nowadays. The best coverage of Wireless LAN depends on performance of the amplifier inside the receiver block diagram. The demand of the first amplifier is low noise that can minimize the noise level of the received signal. The noise will be attenuation, interference, crosstalk and power adjacent which is added during transmission. The amplifier is known as Low Noise Amplifier (LNA). This project present of the Low Noise Amplifier at 2.4 GHz by using ATF 54143. LNA designed involve three different methods which are maximum gain, low noise and specified gain design methods. All the design was simulate in ADS2006 to perform noise figure, s parameters and stability simulations. Maximum Gain method gives maximum value of gain which is 14.549 dB and noise as 0.54 dB. For Low Noise Amplifier method, it gives the minimum value of noise which is 0.0162 dB while gain as 6.742 dB. While for Specified Gain design method, gain produced is 9.774 dB and noise is 0.5 dB.
