Abstract

This project the design of low noise amplifier (LNA) using cascode and cascaded techniques for WiMAX 802.16 standards. The LNA front end receiver is designed to operate at 5.8 GHz in compliant with IEEE 802.16 WiMAX standard. The design process involved the use of design software's such as Advanced Design System (ADS) 2008, and MathCad. Field Effect Transistor (FET) FHX76LP is used in the design of the LNA due to its low noise figure and high input impedance. The LNA is used T lumped reactive element networks and microstrip line matching network. Generally, the design ofLNA consists of two stages. First stage is cascode LNA and follows by second stages is cascaded LNA. A cascode LNA designed for the system produced a g$ of 19.5 dB. The overall performance of the LNA frontend receiver system produced a gain (S21) of 52.8 dB. The overall noise figure (NF) achieved is 1.4 dB and reflection loss (S12) is -76.3 dB. The input reflection (Su) and output insertion loss (S22) are -12.4 and -19.53 dB respectively. The radio frequency bandwidth recorded for the overall stages of LNA is above 1.04 GHz. The input sensitivity is compliant with the IEEE 802.16 standards.
