  • Calibrating the Six-Port Reflectometer Using a Matched Load And Four Unity-Reflection Standards (Part 2) 

    Bilik, V. (Společnost pro radioelektronické inženýrství, 1992-12)
    A convenient and exact method of using a sliding load to the calibration of the single six-port reflectometer is described. Neither reflection coefficient nor positions of the sliding load settings need be known. Reflection ...

  • The Directional Signal Filtering by Progressive Phasing 

    Novacek, Z. (Společnost pro radioelektronické inženýrství, 1992-12)
    The paper deals with a method of signal filtering in the feed network of a phased array. Two alternative ways of phase control are described here. Both of them enable to set several directions of zero reception independently ...

  • Standard Time and Frequency 

    Buzek, O.; Cermak, J. (Společnost pro radioelektronické inženýrství, 1992-12)
    The Institute of Radio Engineering and Electronics of the Czechoslovak Academy of Sciences (IREE), Prague, provides the national primary time a frequency reference for the Czechoslovak metrology. The paper describes main ...

  • The Waveguide Behaviour of the Ballistic Carriers in Confined Qantum States 

    Urban, F.; Allsopp, D.W.E.; Redhammer, R. (Společnost pro radioelektronické inženýrství, 1992-12)
    Peculiar waveguide properties of quantum waveguides are revealed using a new transfer matrix based approach in the numerical analysis of the quantum well structures. The approach is built on the solution of the 2D Schrodinger ...
