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

A split-mount radio unit, comprising:

• an indoor unit;
• and
• an outdoor unit that is connected to the indoor unit via a cable, wherein the outdoor unit further includes:
• an enclosure including a pair of first and second castings, wherein the first casting includes a heat sink;
• an interface card mounted on an inside surface of the first casting, wherein the interface card includes a connector on a surface opposite the inside surface of the first casting;
• a transceiver including a transmitter and a receiver mounted on the inside surface of the first casting, wherein the transceiver includes a first connector on a first side of the transceiver facing the inside surface of the first casting and a second connector and a pair of transmit port and receive port on a second side of the transceiver opposite the first side of the transceiver and the second connector is configured to be connected to a digital card via a flexible circuit, the first connector is connected to the connector of the interface card and the second connector is not in use and the transmit port is coupled to the transmitter and the receive port is coupled to the receiver, respectively;
• a diplexer including a pair of transmit port and receive port on a surface facing the second side of the transceiver and a common port on an opposite surface facing an inside surface of the second casting, wherein the pair of transmit port and receive port of the diplexer are connected to the corresponding pair of transmit port and receive port of the transceiver;
• and
• an antenna outside the enclosure, wherein the antenna includes a port connected to the common port of the diplexer through a hole of the second casting.

An all-outdoor radio unit, comprising:

• an enclosure including a pair of first and second castings, wherein each of the pair of first and second castings includes a heat sink;
• a transceiver mounted on an inside surface of the first casting, wherein the transceiver includes a first connector on a first side of the transceiver facing the inside surface of the first casting and a second connector and a pair of transmit port and receive port on a second side opposite the first side of the transceiver;
• a diplexer including a pair of transmit port and receive port on a first side of the diplexer facing the inside surface of the first casting and a common port on an opposite side of the diplexer facing an inside surface of the second casting, wherein the pair of transmit port and receive port of the diplexer are connected to the corresponding pair of transmit port and receive port of the transceiver;
• a digital card mounted on the inside surface of the second casting, wherein the digital card includes a hole near its center and a connector on a surface opposite the inside surface of the second casting for connecting to the second connector of the transceiver via a flexible circuit;
• and
• an antenna outside the enclosure, wherein the antenna includes a port connected to the common port of the diplexer via a waveguide connection through a hole of the second casting and the hole near the center of the digital card, respectively.
