  1. 1. RF High Power Amplifiers for FREIA – ESS : design, fabrication and measurements

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Linus Haapala; Aleksander Eriksson; [2014]
    Keywords : RF power amplifier; ESS; 352 MHz;

    Abstract : The FREIA laboratory is a Facility for REsearch Instrumentation and Acceleratior development at Uppsala University, Sweden, constructed recently to test and develop superconducting accelerating cavities and their high power RF sources. FREIA's activity target initially the European Spallation Source (ESS) requirements for testing spoke cavities and RF power stations, typically 400 kW per cavity. READ MORE

  3. 2. Development of a wideband high power amplifier for cancer treatment.

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Sohil Shahabi Ghahfarokhi; [2013]
    Keywords : wideband; high power; amplifier; hyperthermia;

    Abstract : Medical hyperthermia refers to heating of tumors to temperature levels which are lethal to the cells for sufficient periods of time or rendering the cancerous cells more sensitive to ionizing radiation or chemotherapy. In order to increase the temperature in cancerous tissues, high power solid state microwave amplifiers need to be used. READ MORE

  4. 3. Multidimensional Measurements on RF Power Amplifiers

    University essay from Institutionen för teknik och byggd miljö

    Author : Edith Graciela Condo Neira; [2008]
    Keywords : Measurements on RF Power Amplifiers;

    Abstract : Measurements are important to specify and verify properties for components, modules and systems. The specifications for a certain figure of merit are usually given in a numerical value or a two dimensional plot. READ MORE

  5. 4. Multidimensional Measurements : on RF Power Amplifiers

    University essay from Institutionen för teknik och byggd miljö

    Author : Hibah Al-Tahir; [2008]
    Keywords : automated multidimentional measurments; RF; power amplifiers; time domain measurements; Gain; efficiency; distortion; three dimensional plots; power sweep; frequency sweep;

    Abstract : Abstract In this thesis, a measurement system was set to perform comprehensive measurements on RF power amplifiers. Data obtained from the measurements is then processed mathematically to obtain three dimensional graphs of the basic parameters affected or generated by nonlinearities of the amplifier i.e. gain, efficiency and distortion.
