Analytical design of a half-mode substrate integrated waveguide Wilkinson power divider

MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 5 2010
A. Suntives
Abstract This article presents a new approach in designing half-mode substrate integrated waveguide Wilkinson power dividers based on analytical relations. Even- and odd-mode analysis is used to determine the required value of the branch resistance and optimize the power divider performance, namely the output ports' isolation. In this manner, the design process for this microwave component is simplified and expedited, while an excellent correlation with full-wave simulations is maintained. Measurements of the fabricated prototype corroborate the calculated results and demonstrate a wide output-port isolation bandwidth of 71%. © 2010 Wiley Periodicals, Inc.

Analysis of microwave components and circuits using the iterative method

INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING, Issue 5 2004
A. Mami
Abstract This article presents an efficient implementation of an iterative method that includes a fast-mode transformation (FMT). The method has the advantages of simplicity and not involving basis functions and inversion of matrices, as used in other calculation methods. Therefore, this approach has the potential to be capable of analysing larger bodies than other classical techniques. An implementation of the iterative calculation is shown for the extraction of S parameters of microwave components and antennas. The good agreement between the simulation results and experimental published data justifies the design procedure and validates the present analysis approach. © 2004 Wiley Periodicals, Inc.

Time-domain measurement and modeling techniques for wideband communication components and systems

INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING, Issue 1 2003
Christopher P. Silva
Abstract The measurement and characterization of RF and microwave components and systems has been dominated by a tone-based frequency-domain paradigm because of its simplicity and accuracy. This review article describes new and accurate time-domain techniques that are superior for application to wideband and nonlinear contexts. © 2003 Wiley Periodicals, Inc.

MMIC's characterization by very near-field technique

MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, Issue 3 2004
L. Nativel
Abstract This paper shows a method to characterize microwave circuits using a near-field scanning microscope. Applied on various samples, it shows good resolution and weak disturbance for ICs operating with very common microwave components. Here, it is applied in an industrial surrounding to characterize the Bluetooth CMOS power amplifier. © 2004 Wiley Periodicals, Inc.
