Description
Summary:This paper presents a novel approach for designing a low noise amplifier (LNA) intended for use in LEO (low earth orbit) satellite systems. The design was based on an MGA 52543 Agilent Technologies manufactured microwave transistor which produces a maximum gain of 15.8 dB and a minimum noise figure of 1.7 dB at the design frequency of 0.9 GHz. Microwave Office software was used in circuit designing and analysis, followed by a prototype implementation by using microstrip technology. The results obtained show that at the design frequency of 0.9 GHz a gain of 15.7 and a noise figure of 1.6 have been achieved, which are quite close to the specified ideal values.
