Broadband Micro-Coaxial Wilkinson Dividers Proceedings Article Ehsan, Negar; Vanhille, Kenneth; Rondineau, Sébastien; Cullens, Evan; Popović, Zoya Resumo | Links | BibTeX | Tags: coaxial, coaxial components, Power dividers @inproceedings{Negar2009Powerb, This paper presents several micro-coaxial broadband 2:1 Wilkinson power dividers operating from 2 to 22 GHz, a 11:1 bandwidth. Circuits are fabricated on silicon with PolyStrataTM technology, and are implemented with 650 um x 400 um air-sup- ported micro-coaxial lines. The measured isolation between the output ports is greater than 11 dB and the return loss at each port is more than 13 dB over the entire bandwidth. The foot- prints of these dividers can be miniaturized due to the high isola- tion between adjacent coaxial lines and their tight bend radius. For higher power handling, larger lines with a cross-section of 1050 um x 850 um are also demonstrated. The effect of mismatch at the output ports is investigated, in order to find the power loss in the resistors. |
