COMPOSITE LC FILTER AND COMPOSITE LC FILTER COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a composite LC filter having high flexibility of design, and a composite LC filter component.;SOLUTION: A composite LC filter circuit 60 comprises a low-frequency side power dual-distribution and composite circuit 52 and a high-frequency side power bi-distribution and composite circuit 53. The low frequency side power bi-distribution and composite circuit 52 has two low-pass filters F11 and F12. The high-frequency side power dual-distribution and composite circuit 53 has two high-pass filters F13 and F14. The low-pass filters F11 and F12 are designed, in such a manner that the pole of the filters F11 and F12 is located in a passing range f2 of the high-pass filters F13 and F14. The poles of high-pass filters F13 and F14 are located in a passing range f1 of the low-pass filters F11 and F12 in the design arrangement.;COPYRIGHT: (C)2003,JPO
