Abstract
Although many fundamental physics auestions are still unanswered, the technology of hightemperature superconductors (HTSs) has become mature for use in wireless Communications. In particular, superconducting filters utilizing HTS epitaxial films can provide better interference rejection, full use of the available freauency spectrum, decrease in the noise floor and size and weight reduction in receiver subsystems. A comparison of the microwave properties between films of high-T e superconductors YBa2Cu3O7-δ and Tl2Ba2CaCu2O8 and medium-T e superconductor Nb3Sn is reported. A first prototype of a superconducting bandpass filter designed to handle a high circulating power and spanning the freauency range from 1710 to 1785 MHz is presented. The implications of its insertion in cellular base stations are discussed. © 2000 Taylor & Francis Group, LLC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
