摘要: 本篇論文主要研究使用耦合共面波導結構研製之微波被動元件,包含耦合共面波導方向耦合器及雙馬爾尚巴倫器。 論文共分兩個部分,第一個部分先將耦合共平波導方向耦合器模擬於TSMC CMOS 0.18 μm的多層金屬結構中。接著利用TSMC CMOS 0.18 μm實作由共面波導方向耦合器組合而成的雙馬爾尚巴倫器,雙馬爾尚巴倫器具寬頻、良好的振幅及相位平衡。最後於TSMC SiGe 0.18 μm上實作降頻正交混頻器,利用耦合共面波導方向耦合器提供寬頻射頻正交訊號及雙馬爾尚巴倫器有效分波本地震盪源訊號,實現射頻及本地振盪源皆為單端輸入的正交射頻單正交混頻器。 第二個部分為使用TSMC SiGe 0.18 μm實作三種不同一二次匝數比的平面式一對二變壓器。
In this thesis, we focus on researching of microwave passive components which include coupled coplanar waveguide directional coupler and dual Marchand balun using coupled coplanar waveguide. This thesis is divided into two parts. In the first part, we simulated coupled coplanar waveguide directional coupler in TSMC CMOS 0.18 μm multi-layer structure, then we implemented dual Marchand balun which is combined of coupled coplanar waveguide directional couplers in TSMC CMOS 0.18 μm process. The dual Marchand balun has broad band property and good balance of amplitude and phase. Finally, we implemented quadrature down converter in TSMC SiGe 0.18 μm process. We implemented quadrature-RF single quadrature downconverter which the both of RF and LO input are single-ended by using coupled coplanar waveguide directional coupler to perform quadrature RF signals and dual Marchand balun to divide LO signal. In the second part, we implemented trifiar transformer of three different turn ratio in TSMC SiGe 0.18 μm process.
