SIS-MIXER RECEIVER WITH SINGLE 140 GHZ TO 170 GHZ RANGE AND ARRAY TUNNEL JUNCTIONS FOR THE R. Blundell, J. Ibruegger, K.H. Gundlach and E.J. Blum ABSTRACT Mixing experiments were made with superconductor-insulator-superconductor (SIS) single tunnel junctions and arrays of junctions. The best receiver noise temperature is 96 K at 150 GHz for a single junction and 67 K at 139.5 GHz for a s

DESIGN USING AND PERFORMANCE DIGITAL CIRCUITS OF MICROWAVE PREDISTORTION NETWORKS M. Horn, A. Egger ABSTRACT The paper deals with a new method for realizing predistortion networks which can compensate with high accuracy for nonlinear amplitude and phase distortions caused by TWT and GaAs FET microwave power amplifiers. The method is based on a digital generation of the nominal nonlinear pre

AN IF-PREDISTORTER FOR TWTA-LINEARIZATION IN 16 QAM DIGITAL RADIO W. Holz * ABSTRACT A predistorter amplifier is described, which linearizes the travelling wave tube of a 140 Mbit/s 16 QAM digital radio system. After discussing the nonlinear behaviour of the TWT, the predistortion circuit is explained. Measurement results show the nonlinear compensation capability of the predistorter. In
