Abstract

Es wird ein Koaxialtransformator mit mindestens zwei parallel nebeneinander angeordneten koaxialen Wicklungsanordnungen (2) vorgeschlagen, jeweils bestehend aus einem inneren Koaxialleiter (3) und einem äußeren Koaxialleiter (4). Die koaxialen Wicklungsanordnungen (2) sind über mindestens einen Planarverbinder (6) miteinander verbunden, wobei der Planarverbinder eine äußere Verbindungsschiene (7) zur Verbindung mit dem inneren Koaxialleiter (3) und eine innere Verbindungsschiene (8) zur Verbindung mit dem äußeren Koaxialleiter (4) aufweist und die innere Verbindungsschiene (8) Durchbrüche (11) zur Durchführung der inneren Koaxialleiter (3) aufweist.

Figure 00000001
A coaxial transformer with at least two coaxial winding arrangements (2) arranged in parallel next to one another is proposed, each consisting of an inner coaxial conductor (3) and an outer coaxial conductor (4). The coaxial winding arrangements (2) are connected to one another via at least one planar connector (6), the planar connector having an outer connecting rail (7) for connection to the inner coaxial conductor (3) and an inner connecting rail (8) for connecting to the outer coaxial conductor (4 ) and the inner connecting rail (8) has openings (11) for the passage of the inner coaxial conductors (3).
