Disclosed is a Doherty power amplification circuit, comprising: a power allocation circuit, and a power amplification circuit connected to the power allocation circuit. Critically, the Doherty power amplification circuit also comprises a combination output circuit connected to the power amplification circuit, the combination output circuit being a rheostatic filter coupler, a rheostatic filter or a rheostatic coupler. The present utility model can be applied to reduce the dimension of a power amplification circuit, reduce the costs of the power amplification circuit and improve the power amplification efficiency. |
