PRINTED CIRCUIT BOARD FOR MOUNTING HIGH FREQUENCY BAND PASS FILTER AND DESIGNING METHOD THEREOF

摘要

PURPOSE: A printed circuit board for mounting a high frequency band pass filter and a designing method thereof are provided to prevent characteristic of a high frequency band pass filter from being changed, minimize change of impedance characteristic, and suppress a frequency band width from becoming narrow. CONSTITUTION: The first pin(40) which is an input terminal, the second pin(50) which is an output terminal, and the third to fifth pins(61-63) which are ground terminals are formed on a PCB. An input terminal of a high frequency band pass filter is mounted on the first pin(40). The second pin(50) is spaced apart from the first pin(40) by a preset distance in a horizontal direction and an output terminal of the band pass filter is mounted. The third pin(61) is interposed between the first pin(40) and the second pin(50). The first pin of a ground terminal of the band pass filter is mounted on the third pin(61). The fourth pin(62) is spaced apart by a predetermined distance from the first pin(40) in a vertical direction, and the second pin of the ground terminal of the band pass filter is mounted. The fifth pin(63) is spaced apart from the second pin(50) by a predetermined distance in a vertical direction, and the third pin of the ground terminal of the band pass filter is mounted.
