The MLC chip BPF has the benefits of low cost and small size. The BPF consists of coulped stripline resonators and coupling capacitors. The BPF is designed to have an attenuation pole at below the passband for a receiver band of IMT-2000 handset. The computer-aided design technology is applied for analysis of the BPF frequency characteristics. The passband and attenuation pole depend on the coupling between resonators and coupling capacitance. The frequency characterics of the passband and attenuation pole are analyzed with the variation of the coupling between resonators and coupling capacitance. An equivanlent circuit and structure of MLC chip BPF are proposed. The frequency characteristics of the BPF is well acceptable for IMT-2000 application. 한국전기전자재료학회 감쇠극을 갖는 적층형 세라믹 칩 필터의 설계 Design of Multilayer Ceramic Chip Band Pass Filter with an Attenuation Pole Article 2 전기전자재료학회논문지, v.16, no.8 전기전자재료학회논문지 16 8 kci ART000892720 MLC Band-pass filter BPF Attenuation pole Stripline
