Abstract:
Systems and methods for improving operational efficiency of a radio frequency system, which includes an antenna amplifier unit that amplifies a data stream while the data stream is being wirelessly communicated and another antenna amplifier unit that amplifies another data stream while the other data stream is being wirelessly communicated. The radio frequency system includes a transceiver amplifier unit coupled to the antenna amplifier unit via an electrical connector, in which the transceiver amplifier unit amplifies the data stream while the data stream is being wirelessly communicated, another transceiver amplifier unit coupled to the other antenna amplifier unit via another electrical connector, in which the other transceiver amplifier unit amplifies the other data stream while the other data stream is being wirelessly communicated, and an electrical connector switching device coupled between antenna-sides of the electrical connector and the other electrical connector.
