HARMONIC DESCRIBING FUNCTION: APPLICATION TO MICROVAVE OSCILLATOR'S DESIGN. Javier Gismero, Jorge Perez. . ABSTRACT A classic description of negative-resistance devices through the first harmonic approach (Describing Function, DF) yields to results that can be insufficiently accurate or even inexact since the harmonic content in the control signals cannot be avoided a priori by the designer

Van Hese, M. Botte and D. De Zutter and Acoustics For the design and simulation of high speed interconnection systems and fast digital computers it is imperative to consider both the two-dimensio

COPLANAR WAVEGUIDE SHORT METALLIZATION THICKNESS W. Menzel, W. Grabherr* CIRCUIT WITH FINITE ABSTRACT Coplanar waveguide is an interesting transmission line alternative for integrated circuits, especially MMICs, as there is no need for substrate thinning and for via holes. For high frequencies and high integration density, the circuit dimensions are becoming very small; therefore metallizatio

ANALYSIS OF THE MICROSTRIP-SLOTLINE CROSSING by M. Beni *, G. Cerri *, A. Morini * and T. Rozzi *# . ABSTRACT Crossings between microstrip and slotline sharing the same substrate provide a flexible design tool encountered in a number of components such as directional couplers, transitions and subsystem as balanced mixers. The present contribution develops a conceptually simple, accurate and h

DISPERSION CHARACTERISTIC ofCOUPLED GUIDES INSET DIELECTRIC T. Rozzit* S. R. Pennock* D. Boscovic* ABSTRACT The inset dielectric quide (IDG) represents an easy-to-fabricate alternative to image line that is also less sensitive to loss by radiation at discontinuities. The propagation constants of single and coupled identical IDGs have been calculated under the LSE approximation. The Transverse

BANDWIDTH CONTROL IN MULTILAYER *t T. Rozzi, S.R. INSET DIELECTRIC GUIDE Pennock t and N. Izzat t ABSTRACT Inset Dielectric Guide (IDG) has shown promise as a transmission media in the microwave and millimetric region in view of its low transmission loss, ease of fabrication and ability to negotiate bends with minimal loss. A newly discovered feature of this guide is its large degree of bandwid

0 dB BANDPASS Sener Uysal and John COUPLER Watkinsl ABSTRACT A new technique is presented for the realisation of 0 dB couplers in microstrip. This new technique involves the minimization of out-of-band coupling in nonuniform directional couplers by modifying the reflection coefficient distribution function. The selection of 0 dB coupling simplifies the theoretical form coupled lines. Theoretical

NOVEL BRANCHLINE CIRCUITS B Mayer, R Knoechel* COUPLERS r'OR MONOLITHIC MICROWAVE INTEGRATED ABSTRACT Novel branchline 3dB-90° and 0°/180° couplers are presented. Solutions are given using distributed lines or lumped elements. A broadbanding procedure for 90°-couplers is outlined, which leads to greatly improved bandwidth with very flat coupling. Element values for lumped-element solutions a
