ABSTRACT:
A distributed constant type delay line device comprises a first base body with a first cutout portion at a bottom corner thereof, a first delay path pattern provided on a first side of the first base body, a first ground conductor provided on a second side of the first base body, a second base body with a second cutout portion at a bottom corner thereof in correspondence to cutout portion of the first base body, a second delay path pattern provided on a first side of the second base body, a second ground conductor provided on a second side of the second base body, in which the second base body is combined with the first base body by contacting the second ground conductor to the first ground conductor such that the first cutout portion on the first base body exposes a part of the second ground conductor at another bottom corner of the second base body and that the second cutout portion exposes a part of the first ground conductor at another bottom corner of the first base body, a pair of input/output pins respectively provided on the first and second base bodies for connection with respective first ends of the first and second delay path patterns, a single jumper provided so as to bridge the first and second base bodies for connecting a second end of the first delay path pattern to a second end of the second delay path pattern, and a pair of ground pins respectively provided on the first and second base bodies for connection with exposed parts of the first and second ground conductors.
