| 摘要 |
The present invention relates to a band pass filter in a parallel coupled line and, more specifically, to a band pass filter in a parallel coupled line to improve selectivity and to improve characteristics of a reflection coefficient by disposing open stoves at the end of an input stage parallel coupled line and the start of an output stage parallel coupled line among a plurality of parallel coupled lines, respectively, to generate a transfer zero at both sides of a center frequency. |
