隨著高頻電路的日益普及與廣泛應用，傳輸速度也大幅提升，因應高頻電路的趨勢，延伸出對量測數據去嵌入的議題。這是由於電氣介面的類型不同，待測物無法直接與向量網路分析儀連接，須透過夾具作為待測物與向量網路分析儀的連接介面，而量測得到的數據會包含夾具的特性，須透過去嵌入技術將夾具的特性移除。因此，如何根據不同的需求，設計適合的去嵌入方案，並確保去嵌入後數據的訊號完整性，成為去嵌入議題的主要任務。
本論文目標是藉由降低設計校正物件的數量，減少量測時不確定性的因素以及量測的時間，將去嵌入技術以更有效率的方式應用到傳輸線，提升實務上的靈活性。然而，隨著量測頻率提高的需求，去嵌入技術在高頻的處理產生問題，訊號完整性隨著頻率升高而降低。本論文藉由提出結合實際數據與模擬分析的方法，探討頻寬限制的原因。從結果可明顯觀察到不同模擬之間訊號完整性的變化，證明本論文探討頻寬限制的原因，最後透過修正不理想因素，在不增加硬體的成本的前提下提升訊號完整性，進而達到延伸頻寬的效果。

In the tendency of increasing popularity and wide application of high-frequency circuits, the transmission speed is greatly improved. In response to the trend of high-frequency circuits, the technique of de-embedding measurement is extended. The device under test cannot be directly connected with the vector network analyzer, because of the different types of electrical interface. It needs to use the fixture as the connection interface between the object under test and the vector network analyzer. The measured data will include the characteristics of the fixture, and the characteristics of the fixture need to be removed by de-embedding. Therefore, how to design a suitable de-embedding scheme, according to different needs and ensure the signal integrity of the de embedded data has become the main task of the de-embedding topic.
The goal of this paper is to apply de-embedding technology to transmission lines in an efficient way and improve the flexibility of practice by reducing the number of design calibration structure, reducing the uncertain factors and measurement time. However, with the increase of measurement frequency, de-embedding technology has problems in high-frequency processing, and the signal integrity decreases with the increase of frequency. In this paper, a method combining actual data and simulation analysis is proposed to explore the causes of bandwidth limitation. From the results, we can clearly observe the changes of signal integrity between different experiments, which proves that this paper discusses the reasons for the bandwidth limitation. Finally, by correcting the undesirable factors, the results can improve the signal integrity without increasing the hardware cost. Therefore, this paper can guide to achieve the effect of extending the bandwidth.
