摘要： A compact single-pole-double-throw (SPDT) switchable bandpass filter (BPF) composed of capacitively loaded multicoupled line is proposed. By replacing the quarter-wavelength impedance transformer at the common junction in conventional designs with a J-inverter, the circuit size is largely reduced and the design procedure is much simplified. As a demonstration, a proposed SPDT switchable BPF is designed and implemented with a center frequency f 0 of 1.0 GHz and a bandwidth of about 10%. Low insertion loss in the on state, good isolation in the off state, and good linearity are obtained. The filter size without bias circuits and input/output traces is only 2.5 cm × 2.7 cm, which is about 0.158 λg ×0.170 λg at f 0. 其他題名： LMWC 出版者： New York, NY: IEEE 出版日期： 2014-02-01 出處： IEEE microwave and wireless components letters, 2014-02, Vol.24 (2), p.87-89 資源來源： IEEE Electronic Library (IEL) 版權： 2015 INIST-CNRS 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
