Patent ID: 8169275

Claim:
A circuit board with jumper structure comprising: a substrate comprising a first plane and a second plane; a ground layer disposed on the second plane of the substrate; a first signal end formed on the first plane of the substrate for receiving a first signal; a second signal end formed on the first plane of the substrate for outputting the first signal; a third signal end formed on the first plane of the substrate for receiving a second signal; a fourth signal end formed on the first plane of the substrate for outputting the second signal; a first signal transmission line formed on the first plane of the substrate, the first signal transmission line comprising: a first signal transfer end; a second signal transfer end; a front transmission line coupled to the first signal end and the first signal transfer end; a first middle transmission line coupled to the first signal transfer end and the second signal transfer end; a back transmission line coupled to the second signal transfer end and the second signal end; and a plurality of ground pads respectively disposed on both sides of the first middle transmission line, each ground pad coupled to the ground layer; and a second signal transmission line formed on the second plane of the substrate, the second signal transmission line comprising: a first signal transmission end coupled to the third signal end; a second signal transmission end coupled to the fourth signal end; and a second middle transmission line coupled to the first signal transmission end and the second signal transmission end; wherein the first signal is transmitted in a microstrip line transmission method between the first signal end and the first signal transfer end and between the second signal transfer end and the second signal end, the first signal is transmitted in a co-planar waveguide method between the first signal transfer end and the second signal transfer end, and the second signal is transmitted in the co-planar waveguide method between the first signal transmission end and the second signal transmission end.
