摘要： A power amplifier comprising a first PCB, a second PCB, a power amplification tube circuit, and a circulator, wherein the power amplification tube circuit is connected to a first end of the circulator by means of a first microstrip line, a second end of the circulator is connected to a second microstrip line, the first microstrip line and the power amplification tube circuit are arranged on the first PCB, the second microstrip line is arranged on the second PCB, and the circulator is arranged on the first PCB or the second PCB. By designing the first PCB and the second PCB, arranging the first microstrip line arranged on the first PCB, and arranging the second microstrip line arranged on the second PCB, only the second PCB of an output end needs to be replaced when a microstrip line of the output end is burnt; and in addition, the power capacity of the microstrip line can be improved by designing microstrip lines with different characteristic impedances.

摘要： A symbol-power-tracking (SPT) voltage supply to power a radio-frequency power amplifier (RF PA) is shown. A power converter is coupled to an output port of an input power source for power conversion, and has an output terminal coupled to a power terminal of the RF PA. A transition capacitor is coupled to the power terminal of the radio-frequency power amplifier through the output terminal of the power converter. An assisted charging and discharging circuit is coupled to the transition capacitor during cyclic prefix (CP) sections. A multi-level array is provided which includes a plurality of voltage-regulated capacitors pre-charged to and kept at different voltage levels. During each symbol section, a target capacitor at a fixed voltage level matching the current SPT situation is selected from among the voltage-regulated capacitors to be coupled to the power terminal of the radio-frequency power amplifier.
