Question

Question3: LNA system design (30pt) A low noise amplifier (LNA) has a noise figure of 2dB, and a nonlinear available voltage with equation y=10x-10x³. We want to achieve a SNR of

10dB in a 160MHz channel. a) Find IIP3 and P1dB in dBm. b) What is the input-referred noise voltage of the mixer to achieve a total noise figure of 3dB? c) What is the spurious-free dynamic range (SFDR)?
