    • 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 ...
    • Probing the extent of the non-thermal emission from the Vela X region at TeV energies with H.E.S.S. 

      Abramowski, A.; Acero, F.; Aharonian, F.; Akhperjanian, A. G.; Anton, G.; Balzer, A.; Pekeur, Nicolette Whilna; Sheidaei, F.; Venter, Christo; Vorster, Michael Johannes; Krüger, Petrus Paulus (EDP Science, 2012)
      Context. Vela X is a region of extended radio emission in the western part of the Vela constellation: one of the nearest pulsar wind nebulae, and associated with the energetic Vela pulsar (PSR B0833-45). Extended ...
    • 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 ...
