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