An RF transceiver front-end includes receiver and transmitter front-ends.
The receiver front-end includes 1.sup.st and 2.sup.nd antennas, a ninety
degree phase shift module and an LNA module. The 1.sup.st and 2.sup.nd
antennas 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 2.sup.nd antenna. The LNA module amplifies
the RF signals received by the 1.sup.st antenna and the shifted RF
signals. The transmitter front-end includes a PA module and 3.sup.rd and
4.sup.th antennas, 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 3.sup.rd antenna transmits the amplified outbound RF signals
and the 4.sup.th antenna transmits the amplified orthogonal outbound RF
signals.
