EVALUATION OF END EFFECTS AND LUMPED CAPACITANCE OF MICROSTRIP WITH ANISOTROPIC SUBSTRATES - TRANSVERSE TRANSMISSION LINE TECHNIQUE Shiban K. Koul* and Bharathi Bhat* ABSTRACT In this paper transverse transmission line technique is used to analyse the lumped capacitance and end effects of microstrip line with anisotropic substrate. In the resulting capacitance expression, the only parameter d

THE HIGH-FREQUENCY CIRCUITS BEHAVIOUR INCLUDING OF MICROSTRIP ENERGY LEAKAGE OPEN ENDS IN MICROWAVE INTEGRATED Joachim Boukamp# and Rolf H. Jansen+ ABSTRACT The complex dynamic behaviour of microstrip open ends in a microwave integrated circuit (MIC) environment, i.e. in the presence of a conducting cover, is analyzed rigorously and discussed under inclusion of energy leakage. Two differe

COMPUTER-AIDED EXPERIMENTAL CHARACTERISATION OF MICROSTRIP-TO-COAXIAL TRANSITIONS H.F. Pues * and A.R. Van de Capelle ** ABSTRACT This paper proposes a novel circuit model for microstrip-to-coaxial transitions and describes a versatile computer-aided experimental technique to determine the model parameters. Only one simple test structure is needed: a two-port consisting of a length of uniform



CORRELATION RADIOMETRY D. BETWEEN AT 11.4 A. FLUCTUATION AND 35 Vander GHz, Vorst EVENTS ON A 11.6 GHz EARTH-SPACE LINK AND AND SPECTRAL ANALYSIS Vanhoenacker, ABSTRACT A quantitative study has been performed on a series of typical fluctuation events. Curves are shown, establishing a relationship between the fluctuations variance and the 35 GHz sky noise temperature. The study of fluct

LOW NOISE SATELLITE Pirmin SYNTHESIZER-BASED EARTH-STATIONS CONVERTER FOR C- TO Ka-BAND Forg* ABSTRACT A converter synthesized noise 1 GHz details are and measured is presented for satellite earth-stations with local oscillator frequencies based on a low surface skimming bulk wave oscillator. Some given on design criteria, components employed, phase noise performances. 

PRACTICAL ASPECTS OF PREDISTORTION DIODE LINEARIZERS FOR SATELLITE TRANSPONDERS D. Cahana* ABSTRACT Experimental and computational evaluations were performed on a predistortion-linearized traveling wave tube (LTWT). Sensitivity of the LTWT to temperature and aging was investigated, and the system performance of a satellite transponder with an LTWT was evaluated for use as a representative commun

A 10 WATT C-BAND GAAS FET POWER AMPLIFIER COMMUNICATIONS SYSTEMS FOR SATELLITE DOWN-LINK J. Czecht A.-M. Khillat M. SchUnzel* ABSTRACT The results of an ESA program to develop a space-qualified solid-state power amplifier (SSPA) and its electronic power conditioner (EPC) as a 16 W TWTA replacement are presented. Not only the microwave performance specifications but also producibility and re

PERFORMANCE OF THE COMMUNICATION SUB-SYSTEM OF AN INTELSAT SATELLITE AFTER 11 YEARS IN-ORBIT - A REPORT Satish Bangara, Khodadad Betaharon* Abstract Two of the first three INTELSAT IV series of satellites, INTELSAT N (F-2) and INTELSAT N (F-3) were launched on 26 January 1971 and 20 December 1971 respectively. Their useful design life was seven years. However, they continued to provide service for
