毫米波無接觸式晶片與基板轉接設計

Abstract

本論文提出一嶄新的無接觸式毫米波轉接設計，是利用共振器與濾波器的原理，在晶片與印刷電路基板(Printed Circuit Board, PCB)上設計半波長共振器，再透過兩共振器之耦合機制，將訊號由晶片傳輸至PCB，形成低損耗且無實質接觸的轉接電路。 論文中的轉接電路是分別在晶片(CMOS 0.18μm)和PCB (Rogers 5880, 5 mil)各設計一半波長共振器，藉由共振器之間的耦合效應，將訊號從晶片有效的傳遞至PCB，其操作頻段為76〜81 GHz。除了設計方式之外，還會討輪轉接電路的容忍度，並且將量測環境和實作結果納入考量，進而修正並改善其設計及量測方式。

In this thesis, a new design of the contactless transition in the millimeter wave are proposed. With the theory of the resonator and filter, half-wavelength resonators are designed on the chip and printed circuit broad (PCB), and then the signal on the chip can be transmitted to the PCB via the coupling mechanism, realizing a low loss transition without any solid line connection between RF circuits. The half-wavelength resonators are designed on the chip (CMOS 0.18μm) and PCB (Rogers 5880, 5 mil) respectively, and the signal can be transimitted from the chip to the PCB efficiently through the coupling effect between the resonators. And the proposed transition is operated from 76 GHz to 81 GHz. Besides, the tolerance of the transition will be discussed. Furthermore, the design will take the measuring environment and results in account to improve the proposed transition and the method of measurement.
