Maximum power gain and minimum noise figure of are equally important in communication receivers. However both cannot be achieved simultaneously also trade-off between these two gives a complex design. In this project a single stage Low Noise Amplifier (LNA) design using Nonlinear MOSFET model have been proposed for X-band applications like radar, satellite ground station services and Direct Broadcast Satellite (DBS) service. Advanced Designed System (ADS) tool has been used to construct and simulate the circuit. The performance parameters of the amplifier such as Noise Figure, Gain, VSWR, 1 dB compression point, Third Order Intercept point (TOI), Harmonic power levels, Dynamic Range are analyzed by considering all device parasitic elements including package parasitic. A hybrid Microwave Integrated Circuit (MIC) which uses minimal microwave discrete components and micro strip transmission lines for biasing and matching networks have been adopted here. Compared to the High Electron Mobility Transistor (HEMT) with three stages, This LNA based MOSFET design provides 11 dB better gain with single stage. The IIP3 is also well improved to 15 dBm rather than −1 dBm reported. The 1 dB compression range is also quite better as 7 dBm.
