    Switchless Bidirectional Amplifier for Wireless Communication Systems
    (John Wiley and Sons Inc., 2007) Aydınlık Bechteler, Ayşe Sevinç; Bechteler, Thomas F.
    A bidirectional amplifier working at 2.4 GHz is presented in this article. The presented amplifier is able to amplify two signals simultaneously. This, since commonly used radio frequency switches are replaced by circulators. The amplifier is designed on a single small-sized printed circuit board. First, the new amplifier circuit is proposed and characterized. Then, its advantages and design problems are analyzed. Finally, design instructions are setup in order to obtain a good performance of the switchless amplifier within the frequency band of interest.

    Analysis of Excitations for a Groove Guide Resonator at 10 Ghz by Means of the Fdtd Method
    (Springer Verlag, 2005) Bechteler, Thomas F.
    Various excitations of a new groove guide resonator working in the X-band (8 GHz - 12 GHz) are investigated by means of numerical simulations. For the numerical simulations the Finite-Difference Time-Domain method is used. The groove guide resonator, modelled both with and without excitation structures, is discretised in space. The results in the time domain are then transformed into the frequency domain in order to obtain the resonance frequency spectrum. Comparison between simulations with and without excitations shows the effect of the excitations on the resonance frequency spectrum. The results are compared with those of previous analytical methods.
