Asymmetric Passive Components in Microwave Integrated Circuits
von Hee-Ran AhnThis book examines the new and important technology of asymmetricpassive components for miniaturized microwave passive circuits. Theasymmetric design methods and ideas set forth by the author aregroundbreaking and have not been treated in previous works. Readersdiscover how these design methods reduce the circuit size ofmicrowave integrated circuits and are also critical to reducing thecost of equipment such as cellular phones, radars, antennas, automobiles, and robots.
An introductory chapter on the history of asymmetric passivecomponents, which began with asymmetric ring hybrids firstdescribed by the author, sets the background for the book. It laysa solid foundation with a chapter examining microwave circuitparameters such as scattering, ABCD, impedance, admittance, andimage. A valuable feature of this chapter is a conversion tablebetween the various circuit matrices characterizing two-portnetworks terminated in arbitrary impedances. The correct conversionhas also never been treated in previous works.
Next, the author sets forth a thorough treatment of asymmetricpassive component design, which covers the basic and indispensableelements for integration with other active or passive devices, including:
* Asymmetric ring hybrids
* Asymmetric branch-line hybrids
* Asymmetric three-port power dividers and N-way powerdividers
* Asymmetric ring hybrid phase shifters and attenuators
* Asymmetric ring filters and asymmetric impedancetransformers
With its focus on the principles of circuit element design, this isa must-have graduate-level textbook for students in microwaveengineering, as well as a reference for design engineers who wantto learn the new and powerful design method for asymmetric passivecomponents.
