摘要: A new compact, low insertion loss, and wide stopband balanced bandpass filter (BPF) with two common-mode (CM) transmission zeros within the differential-mode (DM) passband is designed in this article. The DM filtering topology formed by quarter-wavelength resonators a short stub loaded source-load coupling structure which can generate to improve selectivity suppress harmonic widen stopband. center-loaded step-impedance open be applied misalign CM fundamental resonant frequencies, meanwhile adjust one zero passband. To enhance suppression passband, another created folded 50- input feedline creates first located at 2 f0d ( center frequency of passband) has little effect on in-band lower-stopband performance. Finally, high BPF prototype for WLAN application fabricated. simulated measured results show good agreement. (c) 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:135-141,
