Microwave system
A microwave system comprises an antenna, antenna feed, a radio transceiver, and appropriate cabling among the aforementioned. Cost, performance and reliability improvements are achieved with further integration of these elements and with design improvements in the antenna feed. One improvement is the integration of the radio transceiver with the antenna feed. This improvement has many benefits including the elimination of RF cables and connectors. Another improvement is the utilization of the digital cable to power the integrated radio transceiver and a center fed parabolic reflector. One embodiment is disclosed for a radio gateway supporting OSI layers 1-7 supported by an Ethernet cable. Another embodiment is a radio with a client controller suitable for supporting OSI layers 1-3, and supported by a USB cable.
1. A microwave system comprising:
a center fed substantially parabolic reflector;
a radio transceiver, said transceiver disposed on a circuit board and coupled to at least one substantially cylindrical radiator, said radiator radially disposed on the circuit board and extending orthogonally from a surface of the circuit board;
one or more directors disposed on said circuit board, each director disposed substantially parallel to the cylindrical radiator, and
at least one sub-reflector, said sub-reflector comprising a thin plate disposed on a weather proof cover and said sub-reflector having a substantially concave surface with a focus directed towards the radiator, wherein the circuit board is physically integrated within the feed mechanism of the center fed parabolic reflector,
wherein the radio transceiver is configured to receive power through an Ethernet cable.
2. The system of claim 1 wherein the radio transceiver couples to a passive adapter via the Ethernet cable, which in turn the passive adapter couples to a client station via another Ethernet cable, wherein the passive adapter receives power by a USB cable that is coupled from a client station; whereas the passive adapter is configured to inject power into the Ethernet cable that is coupled to the radio transceiver.
3. The system of claim 2 , wherein the radio transceiver includes a radio gateway supporting OSI layers 1 to 7.
4. A microwave system comprising:
a center fed substantially parabolic reflector;
a radio transceiver, said transceiver disposed on a circuit board and coupled to at least one substantially cylindrical radiator, said radiator radially disposed on the circuit board and extending orthogonally from a surface of the circuit board;
one or more directors disposed on said circuit board, each director disposed substantially parallel to the cylindrical radiator, and
at least one sub-reflector, said sub-reflector comprising a thin plate disposed on a weather proof cover and said sub-reflector having a substantially concave surface with a focus directed towards the radiator, wherein the circuit board is physically integrated within the feed mechanism of the center fed parabolic reflector,
wherein the radio transceiver is configured to receive power through a USB cable.
5. The system of claim 4 wherein the radio transceiver couples to a USB repeater via the USB cable, which in turn the USB repeater couples to a client station via another USB cable.
6. The system of claim 5 , wherein the radio transceiver includes a client controller supporting OSI layers 1 to 3.
