A power supply method and device for a radio-frequency power amplifier are provided, which relates to the technical field of Printed Circuit Boards (PCBs). The method includes: drains or collectors, configured to output amplified signals, of each of multiple radio-frequency power amplifier tubes in a radio-frequency power amplifier unit are directly connected through a first microstrip line; the first microstrip line is connected to a second microstrip line configured for radio-frequency output through a blocking capacitor; a grid or base voltage is correspondingly applied to grids or bases of each of the multiple radio-frequency power amplifier tubes respectively; and a drain or collector voltage is correspondingly applied to the drain or collector of one radio-frequency power amplifier tube in the multiple radio-frequency power amplifier tubes, and then the drain or collector voltage is correspondingly applied to the drains or collectors of the other radio-frequency power amplifier tubes in the multiple radio-frequency power amplifier tubes through the first microstrip line respectively. The design is unique in circuit, flexible layout of a PCB may be implemented, and an increasingly sharp conflict between miniaturization and high power may be resolved. |
