The invention is directed to a method for matching characteristic impedances in a wideband manner. The matching of characteristic impedances is realized by tapering a conductor inside a wall composed of a dielectric material. The tapered conductor is either an asymmetric stripline or an asymmetric coplanar line. The method enables characteristic impedance matching at up to 40 GHz. The coupler is applicable to signal line feedthroughs in MMIC packages. |
