| 摘要 |
<p>The invention provides a filter (10,20), comprising: at least one inductance device (L11, L21, L22), at least one resonator (RES11, RES21, RES22), and at least one switching device (PD11, PD21, PD22). The inductance device (L11, L21, L22) may be connected in parallel with the switching device (PD11, PD21, PD22), and the resonator (RES11, RES21, RES22) may be connected in series with said switching device (PD11, PD21, PD22). The above filter is small in size that is capable of functioning for high-frequency signals of plural frequency bands which are relatively adjacent to each other. <IMAGE></p> |
