	~~'''Impedanz''' ist ein Thema aus dem Bereich der Hochfrequenztechnologie~~. ~~Sie beschreibt die Wechselwirkung der Ausbreitung elektromagnetischer Wellen zwischen einem Signalsender und der Leitung, die das Signal führt~~.		In high frequency PCB designs the impedance of a signal leading medium needs to be recognized. So it is convenient to determine the later width of a track in the layout already in the schematic. This should be possible for single signals or for signal classes as well. It is about the principle of how a strip line should be constructed. ([http://en.wikipedia.org/wiki/Stripline StripLine]).

	Wenn zum Beispiel die Impedanz einer Leitung etwa nicht mit der Eingangsimpedanz eines Gerätes übereinstimmt, kommt es zu Störungen der Signal- oder Leistungsübertragung. Es kommt zu Resonanzerscheinungen durch Reflexionen innerhalb des elektromagnetischen Wellengefüges zwischen Quelle und Leitung was zu einem nichtlinearen Frequenzgang führen kann.		[[Image:stripline.png\|StripLine (Cross section)]]<br>Image: StripLine (Cross section)<br><br>

	~~Bei Leiterplattendesigns für Hochfrequenz-Lösungen wünscht man sich, für einzelne Signale oder ganze Signalklassen bereits im Schaltplan eine möglichst günstige Leiterbahnbreite festzulegen~~. ~~Es geht also um das Bauprinzip einer~~ [~~http~~:/~~/de~~.~~wikipedia.org/wiki/Streifenleitung Streifenleitung~~] ~~([http~~://~~en.wikipedia.org/wiki~~/~~Stripline StripLine]).~~		Open in TARGET 3001! the Impedance calculator either in the dialog ''Edit signal wire'' (Double clock on a signal wire or [e] after having highlighted the signal) or in the dialog ''Edit signal classes'' (menu actions).<br><br>

			* The copper thickness '''t''' of the StripLine
			* The permittivity '''<big>ε<sub>r</sub></big>''' of the dilelectric agens

	~~Folgende Bestimmungsfaktoren spielen dabei eine Rolle:~~		A certain '''Nenn-Impedanz Z''' required, needs resulting from the facts given the required track width '''w''', which can be overtaken to the signal class as standard width.<br><br>
	* Die Mächtigkeit (~~Höhe h~~) ~~des Dielektrikums~~, in ~~das~~ die ~~StripLine eingebettet ist (= Materialkörper der Leiterplatte)~~		Wird der Streifenleiter gedoppelt verlegt (differential StripLine), spielt zusätzlich der Abstand '''s''' der beiden Leiterbahnen zueinander eine Rolle. Analog wird der geeignete Leiterbahnabstand zusätzlich in die Signalklasse als Standard-Leiterbahnabstand übernommen.
	* Die Kupfer-~~Dicke t der StripLine~~
	* Die Durchlässigkeit des Dielektrikums, seine relative Permittivität <big>ε<sub>r</sub></big>

	Eine Vorgeschriebene '''Nenn-Impedanz Z''' erfordert daraus resultierend die '''geforderte Leiterbahnbreite w''', der dann in die Signalklasse als Standard-Leiterbahnbreite übernommen werden kann.<br><br>		[[Image:stripline_d.png\|Der Impedanz-Kalkulator]]<br>Bild: Der Impedanz-Kalkulator berechnet die optimale Leiterbahnbreite und übernimmt den Wert in die Signalklasse<br><br><br><br>
