Overview
In general, the size advantage of normal or superconducting lumped components over distributed components makes them attractive for low-frequency (~0.1 - 20GHz) and broad-band microwave circuits.For some applications with more stringent requirements, the use of metal-oxide superconducting materials such as YBa2Cu3O7 is expected to be advantageous over that of conventional metals such as Au or semiconductors such as GaAs, since the dissipation and dispersion in quality metal-oxide films can be considerably smaller than those in conventional materials at low microwave frequencies (20GHz) and low temperatures (77K). Also, due to their small size, lumped circuit elements can be easily combined with other distributed or lumped-components on a single chip yielding enhanced versatility. Furthermore, lumped components made of superconductor / insulator metal-oxide heterostructures have the unique property that their microwave response can be modulated by electric fields, thus they can form a new class of active microwave components.
