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...
A novel common source three stage microwave integrated circuit (MIC) low noise amplifier (LNA) is designed, analyzed, fabricated and tested at Ku-band. Each stage is operated at 2V–15mA rating to achieve optimum desired gain-noise performance taking care of trade-offs. 30dB gain with 1.4dB minimum noise figure is achieved at 13GHz. Input port is noise matched giving input return loss of −13dB. Power...
