| Abstract(in English) | In this paper, we propose bandpass filters (BPFs) which combined two or more coupled-lines, and assume use of high frequency switches. The transmission characteristics of the proposed BPFs are evaluated by using a circuit simulator and an electromagnetic simulator. We have confirmed that an attenuation pole is obtained at the lower side, the higher side or both sides near the passband by performing appropriately choice of open-circuited end/short-circuited end of the coupled-line, choice of location of the high frequency switches, capacitor loading and others. Furthermore, the experiment about one of the proposed BPFs based on microstrip line structure is carried out, and it compares with the result and simulation result. |
