US Patent 10298275 Outphasing transmit and receive wireless systems having dual-polarized antennas

An outphasing transmitter includes a decomposition block, first and second power amplifiers, and a dual-polarized antenna in a phased array antenna panel. The decomposition block decomposes a composite input signal into first and second decomposed RF signals. The first and second decomposed RF signals are coupled to the first and second power amplifiers. The first power amplifier is coupled to a vertically-polarized probe, and the second power amplifier is coupled to a horizontally-polarized probe. A plurality of dual-polarized antennas may be utilized. The first power amplifier is coupled to each vertically-polarized probe; while the second power amplifier is coupled to each horizontally-polarized probe. Alternatively, the first power amplifier may be coupled to vertically-polarized probes in each odd column, and to horizontally-polarized probes in each even column; while the second power amplifier may be coupled to horizontally-polarized probes in each odd column, and to vertically-polarized probes in each even column.
