 技術摘要 / Our Technology： |
本發明係一種三維轉換式平衡不平衡轉換器，透過數層金屬層以及介電層所構成的電氣結構係形成一等效電路，該等效電路該第一微帶線、第二微帶線、第五微帶線以及第六微帶線形成電氣串聯，該第三微帶線以及第七微帶線形成電氣串聯，該第四微帶線以及第八微帶線形成電氣串聯，且該第三微帶線與第四微帶線分別係接地，並使得該第一微帶線與第三微帶線、該第五微帶線與第七微帶線、該第二微帶線與第四微帶線以及該第六微帶線與第八微帶線分別形成電氣耦合對。其中，該第六微帶線一端電氣延伸形成一輸入埠，該第七微帶線一端電氣延伸形成第一端點，該第八微帶線一端電氣延伸形成第二端點，使得輸入頻率接近平衡不平衡轉換器中心頻率之訊號進入該輸入埠，則該第一端點以及第二端點分別輸出振幅大小相同且相位差180度之訊號。
A three-dimensional balun is disclosed by laminating alternate layers of conductor and dielectric substrate on top of each other to create a microwave circuit. The laminated layers are constructed in a transmission line configuration, corresponding to an equivalent circuit, wherein the first and third transmission lines, the fifth and seventh transmission lines, the second and fourth transmission lines, and the sixth and eighth transmission lines are pairs of coupling lines; one end of the sixth transmission line is defined as an input; one end of the seventh transmission line is defined as a first output; one end of the eighth transmission line is defined as a second output. When signals close to the center frequency of the operating balun are input from the unbalanced side, the signals are converted and then output through the first and second outputs having the same amplitude and producing 180-degree phase shifts.
