Title (EN) A PLANAR TRANSFORMER AND A SPLITTER/COMBINER USING SAME
(FR) TRANSFORMATUER PLAN ET REPARTITEUR/MULTIPLEXEUR EMPLOYANT CE DERNIER
Abstract:
(EN) A planar transformer (100) having substantially co-planar primary (301) and secondary windings (304) is formed through a deposition process on a substrate (101). This transformer has particular utility in a splitter/combiner structure.
(FR) Un transformateur plan (100) ayant un circuit primaire (301) et un circuit secondaire (304) pratiquement dans le même plan est formé par un procédé de déposition sur un substrat (101). Ce transformateur est tout particulièrement utile dans un système de répartiteur/multiplexeur.
