    • Cheap 0.36 dB broadband multipath LNA 

      Krüger, Petrus Paulus (Institution of Engineering and Technology (IET), 2012)
      A two-path low-noise amplifier (LNA) designed for the planned MeerKAT radio telescope is presented. The LNA has a noise figure (NF) of less than 0.36 dB and input return loss of less than 12 dB from 0.7 to 1.8 GHz. It ...
    • A feasibility study of broadband low–noise amplifiers with multiple amplification paths for radio astronomy 

      Krüger, Petrus Paulus (North-West University, 2010)
      Multipath amplifier theory: In this thesis it is proven that the theoretical minimum noise measure of a multipath amplifier (an amplifier which has multiple parallel amplifiers) is achieved by using the optimum source ...
    • Numerical methods to solve the fuel depletion equations for a nuclear reactor 

      Krüger, Petrus Paulus (North-West University, 2004)
      Different numerical methods for solving the fuel depletion equations in the depletion module of a reactor core analysis system are compared with each other, in order to find the best method and the best implementation ...
    • Theory and design of low-noise multipath amplifiers 

      Visser, Barend; Krüger, Petrus Paulus; De Jager, Ockert Cornelis Ocker Cornelis (IEEE, 2011)
      The theoretical minimum noise measure of a multipath amplifier (an amplifier that has multiple parallel amplifiers) is achieved by using the optimum source impedance and optimum gain for each amplification path. This optimum ...
