NOVEL George SYNTHESIZED SOURCE FOR MICROWAVE MEASUREMENT SYSTEM Hjipieris, Tim Pegg. Garry Thorp * ABSTRACT This paper aims to illustrate how the source forming part of modern microwave measurement system can be significantly simplified and improved if it is tailored to a specific measurement task. By first considering the major requirements of such a source namely speed, accuracy, po

BROADBAND HOMODYNE SIXPORT REFLECTOMETER . Bogdan Galwas,Slawomir Palczewski ABSTRACT: The paper presents a new concept of the broadband homodyne sixport reflectometer. Homodyne detection with rectangular phase modulation, which is equivalent of DSBSC modulation is used in the measurement system. The mathematical approach of the reflectometer bases on the mathematical analysis of the sixport re

AN IMPROVED METHOD OF DETERMINING THE REFERENCE CHARACTERISTICS OF SIX-PORT REFLECTOMETERS . PORT V. Bilik ABSTRACT A new method of determining the reference port parameters of six-port reflectometers is presented. The method, resulting from geometrical considerations, can easily be implemented in several existing calibration schemes which do not use Engen's six-port to four-port reduction. Th

Knochel* calibration vector such process for eliminating systems the influence of the image No sideband in homodyne devices measurement is introduced. special calibration First the controlled data the are as reference SSB-modulator lines or phaseshifters system are nec

COMPARISON BETWEEN NOVEL VERY WIDEBAND NETWORK ANALYZER CALIBRATION TECHNIQUES AND THE TRL METHOD Rorert Soares+ , Hien DoKy. ,Daniel Bourreau# , Sara Meszaros. ABSTRACf Very wideband Through-Attenuate-Reflect (TAR) and Through-Attenuate-Network (TAN) methods, suitable for RF probing, are developped in detail, and their performance studied with regard to practical limits in the the standards used.

NETWORK ANALYSIS WITH A SINGLE IMAGE SIDEBAND GENERATOR OF A HIGH B. Schiek and H.-J. Eul . ABSTRACT SUPPRESSION A multistage single sideband generator is described consisting of a cascade of binary periodically switched phase shifters, e.g. with the values 180°, 90° and 45° for a double stage unit. With a special order of phase shift values any degree of suppression of the image sideband

A 2-6 GHz GaAs Monolithic Up-Converter Dan McNamara, Fazal Ali, Tom Holden. ABSTRACT This paper presents the design and performance of a 2-6 GHz GaAs monolithic upconverter with a high level of integration. The upconverter IC consists of a two stage push-pull LO amplifier, a two stage RF amplifier, a two stage IF amplifier and a transformer-coupled double balanced Schottky diode mixer and meas

A NOVEL 1 TO 14 GHz MONOLITHIC and A. H. Aghvami * MATRIX DISTRIBUTED lET MIXER I. D. Robertson ABSTRACT The concept of the matrix distributed amplifier has been extended to the distributed mixer, giving an exceptionally convenient method of isolating the RF, LO, and IF signals. The matrix distributed mixer incorporates RF amplification, mixing, and IF amplification, in a series of tiers of
