You Are Required To Design A Microwave Amplifier With Maximum Gry For Two Way Radio Application At Frequency Of 900 Mhz 1 (82.16 KiB) Viewed 18 times

You are required to design a microwave amplifier with maximum Gry for two-way radio application at frequency of 900 MHz using a GaN HEMT. The measured scattering matrix of the transistor at 900 MHz using 50 2 system is shown in Table 1. Table 1 $11 S12 S21 S22 0.54140⁰ 0 5245° 0.64 - 95⁰ (a) What is the main requirement that need to be considered before you start designing an amplifier? Why it is so important? (b) Determine the maximum Gru- (c) Design matching sections using open-circuited shunt stubs and line lengths. Note: For section (b) and (c) you need to use Smith chart to answer the question.
