In this paper, the authors present the design of triple stages cascoded low noise amplifier using an Inductive Drain Feedback (IDF) technique which operates at frequency 5.8GHz 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 (S21) of 79.16 dB and the Noise Figure (NF) of 0.71dB. The output reflection (S22), input reflection (S11) and return loss (S12) are -12.56, -11.96dB and -100.22dB respectively.
