Abstract

Communication is the most important in our life through rapidly with technology.Since, there are many ways to communicate even through the world.Satellite is one of the part of communication that consist of uplink and downlink.This project will design for downlink satellite at C-Band indicate in microwave spectrum frequency with frequeny 4GHz.This Low Noise Amplifier (LNA) which is located at the front-end of the receiver(ground station). Low Noise Amplifier functioned to amplify the firsts amplication signal and to reduce the noise in the received signal.This will make it harder for the system to read the signal. The objective of this project is to design a LNA with operating frequency at 4GHz. The goal of noise figure(nf2) less than 1.3 dB and gain is over than 10 dB. GaAS FET transistor ATF-54143 from Avago Technology will be used as one of the part Low Noise Amplifier because it meet the specifications Avago Technology and able to used for satellite downlink communication. The simulation for this project will be using Advance Design System 2011. This LNA input and output match by using single stub technique and fabricated by using microstrip technology FR4 as a material. The design was successfully achieved with noise figure(nf2) 1.182dB and reasonable gain(S21) 11.112dB.
