摘要: Wideband bandpass filters using a hybrid ring with shunt open-circuited stub is proposed and developed. The impedances of the determine location transmission zero pair in domain. This controllable can be designed to flatten group delay or improve selectivity filter. Two experimental same circuit topology are realized verify improvement flatness respectively. These two design examples implemented by balanced microstrip line on 20-mil RO4003 substrate. measurement results show excellent agreements electromagnetic simulation.
