技術摘要 / Our Technology:
一種微型化多層型相位混合式信號分配器電路,其功能為完全等效於一傳統之鼠競式耦合器(rat race coupler),但具有完全不同之電路架構,可於積體電路的實現上較傳統之鼠競式耦合器更為微型化。此微型化多層型相位混合式信號分配器電路採用一多層式電路基板來配置複數條傳輸線路,且令各相鄰層上的傳輸線路之間透過隔空之電磁耦合而構成一馬佳得式之平衡對不平衡轉換器(Marchand balun)。此作法可使得具體實施時所需的積體電路佈局面積僅大約為傳統之鼠競式耦合器的10%。

A miniaturized multilayer hybrid-phase signal splitter circuit is proposed, which is fully equivalent in function to a conventional rat-race coupler, but with a specialized circuit layout structure that allows its IC implementation to be more miniaturized than the conventional rat-race coupler. The proposed hybrid-phase signal splitter circuit features the use of a multilayer substrate for the layout of six transmission lines in such a manner that the transmission lines in the middle layer are inductively coupled to the transmission lines on the overlying layer as well as the transmission lines on the underlying layer to form a Marchand balun. In IC implementation, the required layout area is only about 10% of the layout area for the conventional rat-race coupler.
