High Gain Flatness Discrete Low Noise Amplifier for 3 to 5 GHz UWB Operation

This work presents the design of a discrete low-noise amplifier which operates in the 3-5 GHz band. Considering that this amplifier was to be used for the amplification of short modulated pulses, the design efforts were targeted towards achieving a flat gain and a flat group delay in the band of interest, while keeping noise figure under 3 dB. It is shown that the resulting design attains a gain of 14dB±0.2dB in the band of interest and noise figure is less than 2.4 dB.
