发明名称 Dielectric filter and dielectric duplexer
摘要 <p>A dielectric filter (10) is formed of resonators (1a,b,c) connected in series with dielectric coupling windows (2a,b) disposed therebetween. When the dielectric constant of the dielectrics (21) which form the dielectric coupling windows (2a,b) is made different from that of the dielectrics (11) which form the resonators (1a,b,c), the dielectric filter (10) having the same central frequency and a different pass-band width is manufactured without changing the shape and dimensions of the dielectric coupling windows (2a,b). &lt;IMAGE&gt;</p>
