Abstract :
This paper describes analysis and design of low noise amplifier at Ku-band for scatter meter application in weather satellites. The designed LNA performance is briefly analyzed in terms of large signal and small signal nonlinear effects. Sensitivity analysis is carried out with respect to different parameters, operating bias VDS-ID, and input signal RF power. Measured results are plotted in terms of gain, noise figure, 1-dB gain compression point, 3rd order input intercept point, input-output return loss, isolation and stability factor. It is found that the proposed design is robust against the RF power variations.
