EXTREME WIDE RANGE SHAPED FREQUENCY RESPONSE MONITOR Edward Aslan* ABSTRACT An electromagnetic radiation monitor probe is described which provides a frequency sensitivity response that mirrors the response of the radiation protection guide. The resulting read-out is in "Percent of the Standard". Three modes of detection are utilized which provide a shaped response over a 20 dB range and a frequen

TRANSITION CHARACTERISATION FOR DE-EMBEDDING PURPOSES S. R. Pennock*, C. M. D. Rycroft**, P. R. Shepherd* and T. Rozzi* ABSTRACT A technique for characterising transitions between different transmission line media is examined. Applications include development of novel circuit media and use as a de-embedding measurement tool. The technique requires measurement of only two sets of back to bac

A FAST W-BAND SIXPORT NETWORKANALYZER B. Neumeyer* 1. ABSTRACT A Sixport Networkanalyzer working in the frequency range from 90 - 100 GHz is presented. The sixport is especially designed for mm-wave applications. Diode detectors are used as fast power measurement devices. With an IBM PC based system for data acquisition, A/D conversion, error correction and display functions the Sixport setup

THE DETECTION MICROWAVE OF MICROWAVES BY OPTICAL FIBRES - A NEW DEVICE FOR MEASURING POWER L.J.Auchterlonie, A.J. Harris, M.J. Sacco, M. Herbert and J. Lundal ABSTRACT A novel approach to detecting microwave power by the use of optical fibres is described. The technique employs, in differing situations, multimode and single mode fibres in various distinct configurations in waveguide.

DISPERSION SUBSTRATES FINLINE. CHARACTERISTICS OF PLANAR STRUCTURES ON BIAXIAL AND LAYERED MEDIA: APPLICATION TO MICROSTRIP AND F. Medina,*,** H. Baudrand * , M.

This formulation takes into

MULTI-LEVEL PROXIMITY COUPLED TRANSITIONS MILLIMETER WAVE APPLICATIONS FOR MICROWAVE AND H-Y. Yang and N. G. Alexopoulos Abstract The success of microwave and millimeter wave integrated circuits and monolithic arrays will largely depend on the development of highly accurate CAD methods. This article presents precise methodologies to model a variety of proximity coupled transitions which may be

THE RIGOROUS MICROSTRIP ANALYSIS OF STRONGLY COUPLED STEP DISCONTINUITIES IN C. J. Railton and T. Rozzi* ABSTRACT A rigorous formulation for the analysis of strongly coupled step discontinuities in boxed microstrip is presented. Use is made of a variational method in which the transverse E field at the discontinuity is expanded in a suitable set of basis functions. Strongly coupled steps a

CHARACITERIZATION OF MICROS TRIP-TO-SLOTLINE TRANSITION DISCONTINUITES BY TRANSVERSE RESONANCE ANALYSIS Tomoki Uwano, * Roberto SOITentino, * Tatsuo Itoh *** * ABSTRACT A method of analysis is described for characterizing the discontinuities of microstrip-toslotline transition in a rigorous manner. The method of analysis is based on the generalized transverse resonant technique extended here to f
