IPC: H03D7/16
Filed: 1999-08-23
Abstract: PURPOSE: A predistorter is provided to precisely compensate for a signal distortion of a non-linear amplifier when the gain of a variable gain amplifier is varied. CONSTITUTION: The predistorter is applied to a circuit including a modulator(9), a variable gain amplifier(10), and a non-linear amplifier(11). An amplitude detecting circuit(15) detects an amplitude of an input signal(Sr). A gain detecting circuit(16) detects a gain of the variable gain amplifier(10) using a gain control signal(Gc). A first multiplier(30) multiplies the amplitude of the input signal of the amplitude detecting circuit by the gain of the variable gain amplifier and outputs the multiplied result value. A function generator(14) generates a predistortion function corresponding to the multiplied result value. A second multiplier(20) multiplies the input signal(Sr) by the predistortion function of the function generator and outputs the multiplied result value to the modulator.
