摘要

Low noise amplifier is designed at 2.1GHz and 4.6GHz. Matching network is designed using lumped elements. Frequency transformation technique is employed to synthesis lumped element. Stabilization circuit is included for stable LNA throughout frequency range. Simulation result gives gain of 12.03dB and 10.16dB and NF of 0.5818dB and 1.2dB respectively at 2.1GHz and 4.6GHz. Input and output VSWR is 1.71 and 3.4 for 2.1GHz and 1.13 and 1.19 for 4.6GHz respectively. Along with that, LNA is stabilized throughout with (Rollet's Stability Factor) k>1.
