LNA, Radio Frequency, Ladder Matching NetworkAbstract
This paper present a microwave low noise amplifier based on ladder matching networks for Wireless applications. The designed circuit is simulated with Advanced Design System (ADS) software. Specifically, Low Noise Amplifier which is located at the first block of receiver system, makes it one of the important element in improving signal transmition. From the statement above, this study was aimed to design a microwave low noise amplifier for wireless application that will work at 5.8 GHz using high-performance low noise superHEMT transistor FHX76LP manufactured by Eudyna Technologies. The low noise amplifier (LNA) produced gain of 17.2 dB and noise figure (NF) of 0.914 dB. The input reflection (S11) and output return loss (S22) are -17.8 dB and -19.6 dB respectively. The bandwidth of the amplifier recorded is 1.5 GHz. The input sensitivity is compliant with the IEEE 802.16d standards.References
