      An Asymmetric Dual-band HTS Band-pass Filter for American Mobile Phone System

      Abu-Hudrouss, Ammar M.; Jayyousi, Awni B; Lancaster, Michael J (2010)
      The American Mobile Phone System (AMPS) has a very complex frequency allocation which is divided between two operators A and B. Therefore, high performance multiple-band system components are desired in both the downlink ...

      Design of multiple-band microwave filters using cascaded filter elements

      Abu-Hudrouss, Ammar M.; Lancaster, Michael J (Taylor & Francis Group, 2009)
      In this paper, a new approach to design multiple-band microwave filters is presented. A transfer function of a cascade of a low pass prototype filter with one or more band reject filters is calculated. This transfer function ...

      Dual-band HTS filter using modified dual-spiral resonators

      Abu-Hudrouss, Ammar M.; Jayyousi, Awni B; Lancaster, Michael J (IET Digital Library, 2010)
      A symmetric dual-band filter with a centre frequency of 887 MHz is presented. The filter uses a modified structure of dual spiral resonators with interdigital capacitive load. At the same resonant frequency, the resonator ...

      Triple-band HTS filter using dual spiral resonators with capacitive-loading

      Abu-Hudrouss, Ammar M.; Jayyousi, Awni B; Lancaster, Michael J (IEEE, 2008)
      The increasing demand on microwave spectrum for communication systems has been the driving force in the filter industry. Multiple filtering characteristics have become necessary for many filter designs in mobile and satellite ...
