臺灣博碩士論文加值系統

本論文主要分為兩個部份，第一個部份我們提出一個以商業化CMOS製程技術製作在Ku頻段的帶通濾波器，此濾波器採用π型電感耦合架構來達到在矽基板上實現諧振腔所需要的耦合量，藉此達成微小化尺寸及低損耗的表現，此濾波器的中心頻率操作在17GHz，尺寸大小為0.56mm×0.6mm，導通帶所量測到的插入損耗為3.2dB。第二部分，我們提出一新型微型微帶共振濾波器的合成方法，此合成方法是以傳統插入損耗設計方法為基礎，應用於對稱或非對稱微型微帶共振器濾波器架構，此外，我們提出一新型微型微帶共振器佈局，實作於Ku頻段上，在截止帶上有良好的特性表現，所量測到的插入損耗為1.5dB，在特定的頻率上拒斥率有超過40dB的特性表現，另外我們也實作出一非對稱微型微帶濾波器，量測的結果與模擬十分接近同時也驗證所提出的設計觀念。

The thesis is composed of two part. The first study present a Ku-band bandpass filter designed and fabricated with a commercial CMOS technology. The filter utilizes a π-network coupling structure to construct the desired coupling and the resonant tanks on Si substrate with a compact size and the low-loss performance. A 17GHz filter chip was fabricated by 0.18μm CMOS technology. The size of filter is 0.56mm×0.6mm and the measured pass-band insertion loss of filter is about 3.2dB. The second study present a method of synthesizing microwave filters consisting of compact microstrip resonators (CMR). The synthesizing method is based on the conventional insertion-loss design method and can be applied to the design of filters consisting of symmetrical and asymmetrical CMR (ACMR). A new type of CMR layout is proposed to suppress the spurious passband response and applied to the implementation of a Ku-band filter. The measurement of the prototype shows about 1.5-dB insertion loss in the passband and a rejection greater than 40 dB at the specified frequencies. Besides, an ACMR filter operated at Ku-band was also designed and fabricated. The measurement result is also close to the computer simulation result. This demonstrates the effectiveness of the proposed design concept.
