Abstract: “This paper presents a design of Cascode LNA using ladder matching network applicable for wireless applications. It’s using the FHX76LP Low Noise SuperHEMT FET transistor. The LNA designed used Ladder-matching network consisting of lump reactive element at the input and the T-matching network at output terminal. The cascode low noise amplifier (LNA) produced gain of 19.23 dB and noise figure (NF) of 1.03 dB. The input reflection (S11) and output return loss (S22) are -15.3 dB and -12.7 dB respectively. The bandwidth of the amplifier recorded is 1.5 GHz. The input sensitivity is compliant with the IEEE 802.16 standards”
