Active and Quasi-Optical Arrays for Solid-State Power Combining

A quasi-optical component does not require physical transmission lines for interconnection to other components, and achieves higher output power than individual oscillators. This type of array is used in the design of hardware for practical microwave and millimeter-wave applications, such as wireless communications, microwave sensors, and radar.

A detailed and timely overview of recent developments in activequasi-optical arrays

In recent years, active quasi-optics has emerged as one of the mostdynamic fields of contemporary research--a highly unconventionalapproach to microwave and millimeter-wave power generation thatintegrates solid-state devices into a single quasi-opticalcomponent in which all devices operate in unison. This book definesand describes active quasi-optical arrays, reviews the currentstate of the art, and answers numerous basic and technicalquestions on the design, analysis, and application of thesedevices.

The contributors to this volume are leading researchers in thefield who present results and views from government, industrial,and university laboratories and offer a balanced discussion on ahigh technical level. They also offer insight into theapplicability and commercial value of this technology for militarysystems, manufacturing processes, communications, and consumerproducts. Topics presented include:
* Analysis and design methodologies for quasi-optical active arrays
* Power-added and power-combining efficiencies of quasi-opticalamplifier arrays
* Phase-shifterless beam steering in oscillator and amplifierarrays
* Integrating quasi-optical active components into a compactsubsystem
* Design and fabrication of quasi-optical oscillators, amplifiers,multipliers, and tuners
* Characterization and measurement of quasi-optical components
