US Patent 8057109 Transceiver module with dual printed circuit boards

Transceiver modules with dual printed circuit boards. In one example embodiment, a transceiver module includes first and second printed circuit boards (PCBs), a transmitter, a receiver, and a flexible circuit. The first PCB is positioned in a first plane and the second PCB is positioned in a second plane. The transmitter and the receiver are both positioned in a third plane that is offset from the first and second planes. The flexible circuit includes conductive traces that allow electrical data signals to pass between the transmitter and the receiver and the first and second PCBs.
