MINIATURIZED HTS DIELECTRIC MULTILAYER FILTERS FOR SATELLITE-COMMUNICATIONS/

Presently, most communication satellites contain well over a hundred o f filters in their payload, Typical satellite multiplexers use dual mo de cavity or dielectric resonator filters which are large and heavy, A s future advanced electronic systems for satellite communication becom e more complex, they will need even more filters requiring filter mini aturization without performance degradation, Therefore, any improvemen t in filter technology consistent with this requirement could enhance satellite's performance, To reduce the size, weight, and cost of the m ultiplexers without compromising performance, ne introduce a new class oh dual mode multilayer filters consisting of YBa2Cu3O7-delta and LaA lO3 thin films, The multilayer configuration in C-band, for example, o ccupies only 1% of the volume of its dielectric resonator counterpart, Details of the design, fabrication, and testing of these filters will be presented.
