Asymmetric Passive Components in Microwave Integrated Circuits (Hardcover)

This book examines the new and important technology of asymmetric passive components for miniaturized microwave passive circuits. The asymmetric design methods and ideas set forth by the author are groundbreaking and have not been treated in previous works. Readers discover how these design methods reduce the circuit size of microwave integrated circuits and are also critical to reducing the cost of equipment such as cellular phones, radars, antennas, automobiles, and robots.

An introductory chapter on the history of asymmetric passive components, which began with asymmetric ring hybrids first described by the author, sets the background for the book. It lays a solid foundation with a chapter examining microwave circuit parameters such as scattering, ABCD, impedance, admittance, and image. A valuable feature of this chapter is a conversion table between the various circuit matrices characterizing two-port networks terminated in arbitrary impedances. The correct conversion has also never been treated in previous works.

Next, the author sets forth a thorough treatment of asymmetric passive component design, which covers the basic and indispensable elements for integration with other active or passive devices, including:

• Asymmetric ring hybrids
• Asymmetric branch-line hybrids
• Asymmetric three-port power dividers and N-way power dividers
• Asymmetric ring hybrid phase shifters and attenuators
• Asymmetric ring filters and asymmetric impedance transformers

With its focus on the principles of circuit element design, this is a must-have graduate-level textbook for students in microwave engineering, as well as a reference for design engineers who want to learn the new and powerful design method for asymmetric passive components.

本書探討了微小化微波被動電路中的新興重要技術——非對稱被動元件。作者提出的非對稱設計方法和理念是開創性的，之前的著作中並未涉及。讀者將了解到這些設計方法如何減小微波集成電路的尺寸，同時對於降低手機、雷達、天線、汽車和機器人等設備的成本也至關重要。

本書首先介紹了非對稱被動元件的歷史，其中包括作者首次描述的非對稱環形混合器，為本書奠定了基礎。該章節通過檢視微波電路參數（如散射、ABCD、阻抗、導納和圖像）來提供扎實的基礎。該章節的一個有價值的特點是提供了一個在任意阻抗終端的二端口網絡之間的轉換表。這種正確的轉換在之前的著作中也未曾涉及。

接下來，作者詳細介紹了非對稱被動元件設計，包括與其他主動或被動器件集成所必需的基本元件，其中包括：
- 非對稱環形混合器
- 非對稱分支線混合器
- 非對稱三端口功率分配器和N路功率分配器
- 非對稱環形混合器相移器和衰減器
- 非對稱環形濾波器和非對稱阻抗變壓器

由於其專注於電路元件設計原則，這本書是必備的研究生級教材，適用於微波工程學專業的學生，同時也是設計工程師學習非對稱被動元件新且強大的設計方法的參考書。
