A method for a predistortion linearization of a branched signal for a RF amplifier, comprising supplying a branched signal to at least one input terminal ( 2 ); distributing power of the input signal present on at least one input terminal ( 2 ) to a plurality of parallel branch-circuits ( 16, 18, 20 ) as a branched signals by a power distributing circuit ( 4 ); controlling a phase parameter and an amplitude parameter of the branched signals by at least one nonlinear branch-circuit ( 18, 20 ); controlling a phase parameter and an amplitude parameter of the branched signals by at least one linear branch-circuit ( 16 ); combining output branched signals of at least one nonlinear branch circuit ( 18, 20 ) with the output branched signals of at least one linear branch circuit ( 16 ) by a power combining circuit ( 12 ); providing an output branched signal of the power combining circuit ( 12 ) on at least one output terminal ( 14 ). Furthermore, a circuit for a predistortion unit linearizing a signal for a RF amplifier and a layout of a predistortion linearization of a signal for a RF amplifier are disclosed.
