Flexible unified architecture for point-to-point digital microwave radios

A transceiver used in a radio unit for wireless communication, comprises: a circuitry board including a transmitter and a receiver; a first connector on a first side of the circuitry board, wherein the first connector is configured to be connected to an interface card; a second connector on a second side of the circuitry board, wherein the second side is opposite the first side and the second connector is configured to be connected to a digital card via a flexible circuit; and a pair of transmit port and receive port located on the second side of the circuitry board, wherein the transmit port is coupled to the transmitter and the receive port coupled to the receiver, respectively. When the transceiver is part of a split-mount radio unit (SRU), the first connector is connected to the interface card and the second connector is not in use. When the transceiver is part of an all-outdoor radio unit (AOU), the second connector is connected to the digital card and the first connector is not in use.
