| dc.description.abstract | 本論文建立一個通用的設計方法，整合180度混波器及濾波器成單一元件，並具有任意濾波響應及功率分配。首先，以耦合濾波器原理為基礎，可以很容易地合成此特定混波器所需要之耦合係數及品質因子。
為了驗證這個方法可延伸到更高的階數、響應及功率分配，本文使用微帶線共振器研製三種180度混波器，所需的同相與反相之相位響應可以利用共振器之間的電耦合、磁耦合或混和型耦合實現。實際電路結構中共振器之間及饋入端的耦合量需滿足此設計方法所計算的耦合量，模擬及量測結果顯示其響應與目標的相符，且電路面積相較於傳統的環形耦合器縮小約65% ~ 80%。當選用的共振器縮小時，電路面積可再減少。因此，以此方式所實現之180度混波器不只達到縮小面積的目的，也同時確保頻率的選擇度。 本文將此方法所合成的耦合係數及品質因子，以低溫陶瓷共燒技術之基板合成波導實現，設計概念是將所有共振腔擺放在同一平面，以減少量測時所需要的額外轉接，並根據TE101模態場型的分布實現不同的平面式耦合機制以達到所需的相位響應。本論文研製兩種具二階柴比雪夫響應但不同功率分配之平面型疊層波導180度混波器於Ka頻帶上，並加以量測以驗證此設計概念。 | zh_TW |
| dc.description.abstract | This thesis focuses on integrating a 180° hybrid and bandpass filters into a single device, and establishing a general method to achieve an arbitrary filtering response and power division. To begin with, based on the groundwork for the coupled-resonator filter design, it provides an easier way to synthesize the required coupling coefficients, and the external quality factors.
Next, in order to verify that this method is flexible and can be extended for different orders, responses and power division ratios, three examples of 180° hybrids using microstrip resonators are presented. In-phase or out-of-phase response of the 180° hybrid is realized by electric coupling, magnetic coupling, or mixed coupling between adjacent resonators. Its physical dimensions should satisfy the calculated coupling coefficients, and external quality factors. Simulated and measured results agree well with the design specification. In comparison to the conventional rat-race coupler, a size reduction of 65% ~ 80% can be achieved. In addition, the circuit size will be further miniaturized if smaller resonators are adopted. As a result, this method has the advantages of not only reducing the circuit size but also ensuring frequency selectivity. By using the proposed method, SIW filtering 180° hybrids can also be implemented in the LTCC technology. The idea is to arrange all cavities in the same plane, so that no additional transition is required for measurement. According to the field pattern of TE101 mode, two types of planar coupling mechanisms are investigated to fulfill the required phase response of the 180° hybrid. Two Ka-band Chebyshev filtering 180° hybrids with different power division ratios are designed to verify the approach. | en |
