A COMPACT COUPLING STRUCTURE FOR DIPLEXERS AND FILTERING POWER DIVIDERS

Using a VIA-Less CRLH Transmission Line to Design Compact Wilkinson Power Dividers and Rat-Race Couplers

A method for design and implementation of a compact via-less Composite Right/Left-Handed Transmission Line (CRLH TL) is presented. By introducing a new circuit model, the CRLH transmission line behavior is studied versus the parameters variations to achieve the desired characteristic impedance and electrical length. Then a compact quarter wavelength CRLH transmission line with 70 Ω characte...

High Power Analysis of Filters and Diplexers

High-power microwave diplexers for advanced ECRH systems

In Electron cyclotron resonance heating systems, high-power multiplexers can be employed as power combiners, adjustable power dividers, fast switches to toggle the power between two launchers, as well as frequency sensitive directional couplers to combine heating and diagnostic applications on one launcher. In the paper, various diplexer designs for quasi-optical and corrugated waveguide transm...

Power Aware Dividers in FPGA

This paper surveys different implementations of dividers on FPGA technology. A special attention is paid on ATP (area-time-power) trade-offs between restoring, non-restoring, and SRT dividers algorithms for different operand widths, remainder representations, and radices. Main results show that SRT radix-2 present the best ATP figure. In combinational implementation, an important power improvem...

Power Comparison of Srt and Gst Dividers

Generally divider algorithms can be separated into two diierent kinds of algorithms, the Multiplicative Algorithms (MA) and the Iterative Digit Recurrence Algorithms (IDRA). The number of iterations of the MA and IDRA are proportional to log 2 (word?length) and the word-length, respectively. However every iteration of the MA consists of two multiplications and one addition, while the iteration ...
