Patent ID: 7639510

Claim:
A repeater card, comprising: a printed circuit board having a ground layer and a power layer separated by a dielectric with the ground layer having a chassis ground plane, a logic ground plane, and a first channel ground plane, and with the power layer having a logic power plane and a first channel power plane, wherein the logic ground plane substantially overlaps with the logic power plane and the first channel ground plane substantially overlaps with the first channel power plane; a DC-DC converter mounted to the printed circuit board and electrically linked to the logic ground plane, the logic power plane, the first channel ground plane, the first channel power plane, and the chassis ground plane; a transceiver mounted to the printed circuit board and electrically linked to the DC-DC converter through the logic ground plane, the logic power plane, the first channel ground plane, and the first channel power plane; and a first amplifier mounted to the printed circuit board and electrically linked to the transceiver, the first amplifier also being electrically linked to the DC-DC converter through the first channel ground plane and the first channel power plane; and further comprising a second amplifier mounted to the printed circuit board and electrically linked to the transceiver, and wherein the ground layer also has a second channel ground plane and the power layer has a second channel power plane, wherein the second channel ground plane substantially overlaps with the second channel power plane and wherein the transceiver, the second amplifier, and the DC-DC converter are electrically linked to the second channel ground plane and the second channel power plane.
