<p>The present invention provides a circulator power amplifier circuit and a connection method thereof. Wherein, the circulator power amplifier circuit includes a power amplifier, a circulator, a power load and a load. An output end of the power amplifier is connected to an input end of the circulator, the load is connected to an output end of the circulator and the power load is connected to the load end of the circulator, wherein, the circulator is an N-stage circulator or an M-port circulator, where both N and M are integers greater than one. The above circulator power amplifier circuit connected through using the circulator power amplifier circuit connection method increases the isolation for the circulator, and it is of great significance in terms of improving a standing wave of the power amplifier, ensuring stability of specification, preventing mismatch damages of the power amplifier and increasing reliability of the power amplifier.</p> |
