本論文以毫米波頻段之三頻積體化被動電路為研究目標，提出使用三頻橋式T線圈(Bridged-T Coil, BTC)等效三頻傳輸線的設計方法，成功實現積體化之三頻分支線耦合器及威爾金森功率分配器。本研究在已有的三頻橋式T線圈設計理論基礎上進行設計公式的簡化，並探討提升設計自由度的方式，所完成之微型化三頻分支線耦合器以WIPD製程實現，其操作頻率為9.1 / 18.5 / 24.2 GHz，電路面積僅1.792 mm × 1.544 mm，於第一操作頻率9.1 GHz之電氣尺寸為0.068λ₀ × 0.059λ₀；於第三操作頻率24.2 GHz之電氣尺寸則為0.146λ₀ × 0.126λ₀。此外，並分別以WIPD製程與TN90GUTM製程實現微型化三頻威爾金森功率分配器，其中以WIPD實現之微型化三頻威爾金森功率分配器操作頻率為16 / 37 / 47.4 GHz，電路面積僅0.852 mm × 0.855 mm，於第一操作頻率16 GHz之電氣尺寸為0.0454λ₀ × 0.0456λ₀；於第三操作頻率47.4 GHz之電氣尺寸則為0.135λ₀ × 0.135λ₀。而以TN90GUTM製程實現之微型化三頻威爾金森功率分配器之操作頻率為13.1 / 36 / 47.3 GHz，電路面積僅0.61 mm × 0.46 mm，於第一操作頻率13.1 GHz之電氣尺寸為0.0267λ₀ × 0.0201λ₀，於第三操作頻率47.3 GHz之電氣尺寸則為0.0962λ₀ × 0.0725λ₀，相較於既有之相關設計，均成功達成大幅縮減電路面積之目的。

摘要(英)

This paper aims to the development of tri-band integrated passive components in the millimeter-wave frequency range. The design methodology of utilizing the bridged-T coil (BTC) to implement tri-band transmission line equivalent is proposed, leading to the successful realization of miniature tri-band branch-line couplers and Wilkinson power dividers. Building upon existing theory of tri-band BTC design, this study simplifies design equations and explores practical methods to enhance design flexibility. Specifically, the proposed miniature tri-band branch-line coupler operating at 9.1/18.5/24.2 GHz is realized using the WIPD process with a circuit area of only 1.792 mm × 1.544 mm. The corresponding electrical sizes at the first and third operating frequencies are 0.068λ₀ × 0.059λ₀ and 0.146λ₀ × 0.126λ₀, respectively. Additionally, the WIPD and TN90GUTM processes are used to implement the proposed miniature tri-band Wilkinson power dividers. The proposed tri-band Wilkinson power divider in WIPD operates at 16/37/47.4 GHz, and it features a compact circuit area of 0.852 mm × 0.855 mm. The corresponding electrical sizes at the first and third operating frequencies are 0.0454λ₀ × 0.0456λ₀ and 0.135λ₀ × 0.135λ₀, respectively. On the other hand, the proposed miniature tri-band Wilkinson power divider in TN90GUTM operates at 13.1/36/47.3 GHz, and the circuit size is only 0.61 mm × 0.46 mm. The corresponding electrical sizes at the first and third operating frequencies are 0.0267λ₀ × 0.0201λ₀ and 0.0962λ₀ × 0.0725λ₀, respectively. Compared to existing designs, the proposed tri-band passive components all achieve significant reduction in circuit area.
