Broadband Amplifier at 8-16 GHz

BALANCED BROADBAND AMPLIFIER 8 to 16 GHz By Maninderjit Singh Hari Master of Science in Electrical Engineering A Balanced Broadband Amplifier operating in the octave of 8 to 16 GHz, providing a gain of 13db at the center frequency of 12GHz, is demonstrated in this project report. It is termed as Balanced Amplifier because two Single stage Maximum gain Amplifiers are connected to each other through a balanced configuration using Lange couplers at the source and load end. This Amplifier provides a low noise figure of 0.6dB comparatively very low to the gain. A hetero-junction field effect transistor named NE4210S01, manufactured by the NEC Corporation 1999, is used for the design due its stability and very low noise characteristics. Microstrip Line Calculations were done based on RO3010 laminate material obtained from the Rogers Corp. The design of the DC biasing circuit, MGA , Lange coupler and the final Broadband Amplifier were designed in the Microwave AWR Environment and the final calculations were verified using MATLAB and Microwave Ebook software. The References leading to any type of figures or information involved in this project are mentioned in the appendices of this report.
