摘要： An apparatus comprises a transceiver (Tx/Rx) printed circuit board (PCB) with a top surface and a bottom surface and a power supply PCB. The Tx/Rx PCB includes two transmitter devices, each comprising a number N of channels. A first transmitter device is arranged on the bottom surface and a second transmitter device is arranged on the top surface over the first transmitter device. One or more pins of the second transmitter device are shorted with one or more pins of the first transmitter device with the same function. An analog front end (AFE) device comprising N input channels is arranged on the top surface of the Tx/Rx PCB, and a digital signal processor is coupled to the AFE device. The power supply PCB comprises a power supply module configured to provide a plurality of supply voltages to the Tx/Rx PCB and the power supply PCB.
