High-Temperature Superconducting Microwave Circuits

This book presents the fundamental principles of high-temperature superconducting (HTS) microwave circuits and shows you how to analyze, design, characterize, and test the circuits you create.

Introduction - history, low temperature, superconductivity, high temperature superconductivity; materials and characterization - substrates and characterization, HTS materials and processing, theory, critical temperature characterization, surface resistance characterization, critical current density characterization, nonlinear effects; transmission lines - parallel plate transmission lines, general theory, HTS transmission lines, applications for HTS transmission lines; passive components - resonators, filters, multiplexers, power splitters/combiners, HTS switches, phase shifters, antenna and feed systems; active devices - Josephson junctions and effects, HTS Josephson junctions, superconducting quantum interference devices (SQUIDS), microwave applications of Josephson junctions; HTS/III-V device hybrid cricuits - device characterization, hybrid amplifiers, hybrid oscillators, hybrid balanced mixers, hybrid receiver front end; high Q-value resonators - theory, test set-up and experimental results, sensitivity of high Q TE011 mode, other high Q resonators, applications; packaging - interconnections, packaging materials, packaging structures; the future - the extremists were wrong, selective applications, niche markets, one key and two milestones.
