Abstract: 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.

Abstract: In examples, an electronic device comprises a semiconductor package including a semiconductor die and a set of conductive members coupled to the semiconductor die, the set of conductive members coupled to a bottom surface of the semiconductor package. The package also includes a conductive terminal coupled to the semiconductor die and exposed to the bottom surface, the set of conductive members extending farther away from the bottom surface of the semiconductor die than the conductive terminal extends from the bottom surface of the semiconductor die. The electronic device includes a flexible substrate having first and second ends opposing each other, the first end having a first conductive terminal coupled to the conductive terminal. The second end has a second conductive terminal adapted to be coupled to an electronic component, the first and second conductive terminals are coupled to each other, and the flexible substrate has a bottom surface that does not extend farther away from the bottom surface of the semiconductor package than the set of conductive members extends from the bottom surface of the semiconductor package.
