Patent ID: 8693468

Claim:
An apparatus comprising: a printed circuit board (PCB) having: a top surface; a bottom surface; and a plurality of serializer/deserializer (SerDes) lanes; an input/output (IO) circuit having a transceiver that is secured to the top surface of the PCB, wherein the transceiver includes: a SerDes circuit that is coupled to the plurality of SerDes lanes; an intermediate circuit that is coupled to the SerDes circuit; a transmitter that is coupled to the intermediate circuit; a receiver that is coupled to the intermediate circuit; and an antenna that is coupled to the transmitter and the receiver, wherein the transmitter and the antenna are configured to provide a millimeter wave transmit link at a first frequency in a direction that extends from the top surface of the PCB, and wherein the receiver and the antenna are configured to provide a millimeter receive link at a second frequency in the direction that extends from the top surface of the PCB; wherein the millimeter wave transmit and receive links further comprise a first millimeter wave transmit link and a first millimeter wave receive link, and wherein the IO circuit further comprises a relay circuit that is secured to the bottom surface of the PCB and that is substantially aligned with the transceiver, wherein the relay circuit is configured to provide a second millimeter wave receive link in the direction that extends from the bottom surface of the PCB.
