4. 3. Design of a Low-Noise Amplifier for Radar Application in the 5 GHz Frequency Band

   University essay from Högskolan i Gävle/Elektronik

   Author : Javier Alvaro Rivera Suaña; [2017]
   Keywords : ;

   Abstract : The purpose of this project was to design and manufacture a Low-Noise Amplifier (LNA) working at a 5 GHz frequency band, by using High Electron Mobility Transistor (HEMT) from Avago Technologies. To improve our design, it was necessary to build a two-stage amplifier; one stage to work in minimum noise sensitivity, and another stage to get the maximum gain achievable by the transistor.

5. 4. Behavioral Modeling of Power Amplifier with Memory Effect and Linearization Using Digital Pre Distortion

   University essay from Högskolan i Gävle/Elektronik

   Author : Om Prakash Nandi; [2016]
   Keywords : Behavioral Modeling; Power Amplifier; DPD;

   Abstract : This thesis work studied the behavioral modeling, estimation of parameters, model performance and linearization of power amplifier (PA) using Digital Pre Distortion (DPD) technique. PAs are one of the fundamental block in communication systems and also one of the main sources of nonlinearities in the system, as these devices are frequently subjected to signals characterized by considerable bandwidths and non-constant envelopes due to use of modern modulation technique.
