Abstract—This project presents a design of low noise, high gain LNA a 5.8 GHz with cascode and cascaded techniques using T-matching network is applicable for IEEE 802.16 standard. The amplifier use FHX76LP Low Noise Super HEMT FET. The LNA designed used T-matching network consisting of lump element reactive element at the input and the output terminal. The cascode and cascaded low noise amplifier (LNA) produced gain of 36.8dB and noise figure (NF) at 1.3dB. The input reflection (S11) and output return loss (S22) are -11.4dB and -12.3dB respectively. The bandwidth of the amplifier is more than 1GHz. The input sensitivity is compliant with the IEEE 802.16 standards.
