ABSTRACT:
An RF transceiver front-end includes receiver and transmitter front-ends. The receiver front-end includes 1stand 2ndantennas, a ninety degree phase shift module and an LNA module. The 1stand 2ndantennas receive inbound RF signals and provide a first directional circular polarization. The ninety degree phase shift module phase shifts the RF signals received by the 2ndantenna. The LNA module amplifies the RF signals received by the 1stantenna and the shifted RF signals. The transmitter front-end includes a PA module and 3rdand 4thantennas, which provide a second directional circular polarization. The PA module amplifies outbound RF signals to produce amplified outbound RF signals and amplified orthogonal outbound RF signals. The 3rdantenna transmits the amplified outbound RF signals and the 4thantenna transmits the amplified orthogonal outbound RF signals.
