An radio frequency amplifying circuit includes an amplifying transistor configured to amplify a radio frequency signal input to a base of the amplifying transistor via a matching network to output the amplified radio frequency signal, a first bias transistor connected to the amplifying transistor based on a current-mirror connection to supply a bias to the amplifying transistor, and a second bias transistor connected to the base of the amplifying transistor based on an emitter-follower connection to supply a bias to the amplifying transistor.
