摘要：
This paper presents two miniaturized LTCC bandpass filters with wide stopband. By selecting suitable coupling region, the discriminating coupling mechanism is realized, which can suppress harmonics without impact on passband performance. Based on the scheme, two bandpass filters are designed. The first one realizes third harmonic suppression in coupling region between feeding line and resonator. The second one owns wide stopband by using discriminating coupling region between resonators. Both two filters are fabricated using LTCC techniques. The size is 0.057 kgx0.039,gx0.032 kg and 0.058 kg x 0.058 kgx 0.011 respectively. The simulated and measured results of the demonstrated LTCC bandpass filters are presented to validate the proposed design.
