<p>Provided in the present invention are a circulator power amplifier circuit and a connection method therefor. The circulator power amplifier circuit comprises 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 of the circulator, where the circulator is an N-level circulator or an M-port circulator, and where both M and N are integers greater than one. The circulator power amplifier circuit connected using the circulator power amplifier circuit connection method increases the degree of isolation for the circulator, and is of great significance in terms of improving power amplification standing wave, of ensuring indicator stability, of preventing power amplifier mismatch damages, and of increasing power amplification reliability.</p> |
