Abstract [en]

The main purpose of this master thesis work was to design and implement an ultra-wideband 3.1-4.8 GHz low-noise amplifier. Moreover, a deeper understanding of the design process when creating a RF application was expected.

The design starts on the schematic level where amplifier is matched to a 50 §Ù termination. First the match was done with lumped components and then with distributed components. The multi-section matching networks were made using two microstrip stubs to achieve a wider bandwidth. The design was then carried on to the layout level where finally the entire circuit was implemented in a PCB. The design and all the simulations were made using ADS from Agilent Technologies Inc.

The PCB was manufactured, assembled and finally measured with a network analyzer. This report shows a functional design with an approximate gain of 10 dB and a noise figure of 2.6 dB at the highest.
