Power amplifier linearization is employed in a variety of microwave communication systems. It is an effective method that results in significantly higher output power operation for the power amplifier. Without Linearization, system constraints, such as intermodulation noise, spectrum spreading and BER performance, make it necessary to operate the power amplifier in a backed off mode.  2, record 4, English, - backed%2Doff%20mode

The microwave beam from the satellite solar power station(SSPS) is triggered by a pilot signal beamed from the center of the receiving antenna to provide the necessary phase control to produce a coherent beam. Otherwise, if the beam were to drift, its coherence would be lost, the energy dissipated, and the resulting power density would approximate normal communication signal levels on Earth.  2, record 5, English, - satellite%20solar%20power%20station
