Design Of Two Stage Microwave Amplifier At 10 Ghz

This project is to design a two stage microwave amplifier with an overall gain of 29 dB and an overall noise figure less than or equal to 1 dB. The two stage microwave amplifier design consists of a Minimum Noise Amplifier Stage (MNA) followed by a Maximum Gain Amplifier Stage (MGA). For the amplifier design, I have used the RFMW essentials software which is provided by my professor Matthew M. Radmanesh, which helps to calculate the baseline solution, which is later used to design the two stage amplifier. Along with that I have used Agilent Technologies'Advanced Design System Software (ADS)' to design the amplifier and also to calculate the required values for impedance matching. I have performed the simulations for the two stage amplifier design. I have used the transistor NE 3210S01 from NEC vendor for the two stage amplifier design. After transistor selection, I have calculated the DC biasing circuit for the two stage amplifier design. Then each stage is calculated using the ADS software and the results are displayed in the report individually for minimum noise stage and maximum gain stage. Then I have cascaded the two circuits and have achieved the overall gain of the project as 28.3dB and an overall noise figure of 0.8dB. Along with that VSWR, overall noise, S-parameter sweep and power gain simulation results of two stage amplifier design is simulated and the results are displayed.
