Title: Filter circuit
Inventor: NISHIKAWA TOSHIO
IPC: H01P5/19
Filed: 1991-08-27
Abstract: PURPOSE:To reduce the size and cost of a filter circuit by connecting at least two band pass filters(BPFs) having respectively different pass bands in series and parallel. CONSTITUTION:The filter circuit 1 is constituted of storing BPFs 2, 3 in a case, connecting between the BPFs 2, 3 through lead wires, mounting the BPFs 2, 3 on a substrate on which connection lines are formed by strip lines and connecting the BPFs 2, 3 through the strip lines. A signal inputted from the input terminal Pi of the circuit 1 is inputted to both the BPFs 2, 3, and since the BPF 2 removes signals other than a pass band DELTAW1 and BPF 3 removes signals other than a pass band DELTAW2, only a signal within a range between the pass bands DELTAW1 and DELTAW2 is extracted from an output terminal Po. Consequently the necessity of a power distributer can be eliminated and the size and cost of the filter circuit 1 can be improved.
