| | Session 3-1 | A New Method for Determining the Characteristic Impedance Zc of Transmission Lines Embedded in Symmetrical Transitions | - | J. E. Zuñiga-Juarez, J. A. Reynoso-Hernandez, A. Zarate- de Landa, CICESE, Ensenada, Mexico |
(16) | Abstract.- In this paper we present a new method for calculating the characteristic impedance of the transmission lines embedded in identical, symmetrical and reciprocal transitions. For calculating the matrix elements of the transitions as well as the characteristic impedance Zc of the lines, the proposed method uses measurements of two different lengths of transmission lines. | | |
Session 3-2 | Analysis and Design of Impedance Transformed Balun Integrated Microwave Probe for Differential Circuit Measurement | - | J. Kim1, W. R. Eisenstadt1, M. Andrew2, P. Hanaway2, 1University of Florida, Gainesville, United States, 2Cascade Microtech Inc, Beaverton, United States |
(22) | This paper presents an integrated broadband balun probe for differential circuit measurements. The balun consists of the two broadside coupled coplanar strips with a finite ground plane. A new analysis method for the Marchand balun is developed for optimizing design parameters. The design parameters are calculated from newly developed conformal mapping analytic expressions. This method verifies the serious effects of the ground plane width variation in a broadside coupled CPS. Final balun design shows a very wide bandwidth (20~100GHz) with small phase difference ( 5°). | | |
Session 3-3 | Comparison Of A Single Channel And A Dual Channel Microwave Attenuation Measurement System | - | T. Y. Wu, S. W. Chua, National Metrology Center, Singapore, Singapore |
(18) | The performance of a single channel microwave attenuation measurement system is compared to a dual channel implementation. The results show that a single channel system is more suitable for attenuation measurement from 10 MHz to 4 GHz since it can cover this frequency range using only two bands, while a dual channel system has to be used for attenuation measurement from 4 GHz to 26.5 GHz since the receiver reading is more stable in this frequency range. | | |
