This paper presents the design of triple stages cascoded low noise amplifier using an inductive drain feedback (IDF) technique which operates at frequency 5.8 GHz for WiMAX application. The triple stages cascoded LNA was designed using the inductive drain feedback, inductive generation to the source, and the T-network at the input and output terminal as a matching technique. This LNA produced a gain (S 21 ) of 79.16 dB and the noise figure (NF) of 0.71 dB. The output reflection (S 22 ), input reflection (S 11 ) and return loss (S 12 ) are -12.56, -11.96 dB and -100.22 dB respectively. The measured 3dB bandwidth of 1.76 GHz has been achieved. The input sensitivity is -92 dBm exceeded the standards required by the IEEE 802.16. The amplifier it is implemented using superHEMT FHX76LP transistor devices. The designed circuit is simulated with Ansoft Designer SV.
