具有阻带抑制特性的微带带通滤波器设计
Design of microstrip bandpass filter with upper-skirt frequency suppression
摘要
Abstract
By the transmission line theory, the paper introduced a transmission zero using a parallel microstrip open-stub line. A proposed filter with 1.9 GHz center frequency, 2％ fractional bandwidth was designed based on dual mode microstrip resonator. The simulation and measurement results of the proposed filter are in good agreement and show the excellent characteristics of up-skirt suppression. The proposed filter can be used for the design of high performance microstrip bandpass filter and diplexers.关键词
