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