摘要: Two compact low-temperature co-fired ceramic (LTCC) wideband bandpass filters using coupled lines with open/shorted stubs are proposed in this paper. conventional used to increase the passband order for filters. independent transmission zeros realized by further improve selectivity and harmonic suppression. Due 3-D LTCC circuit, can be located at different layers overcome large circuit size. fifth-order centered 3.1 GHz multiple designed fabricated verification. The theoretical measured results good agreement show in-band performances.
